Abstract :

With the advancement of science and technology, traditional energy sources such as oil and coal have been extensively depleted, leading to the emission of greenhouse gases like CO2. Consequently, issues such as energy scarcity and drastic environmental changes have emerged as pressing concerns that threaten human survival and development. Photocatalysis offers a promising solution by harnessing solar energy for chemical energy conversion, yielding clean and sustainable products. It is widely regarded as an emerging approach to address the energy crisis and environmental challenges. To achieve high-efficiency photocatalytic reactions, the selection of appropriate catalysts and co-catalysts plays a pivotal role. However, conventional photocatalysts such as TiO2, CdS, and g-C3N4 suffer from inherent limitations, including high charge recombination rates, low light utilization efficiency, poor stability, and sluggish charge transfer kinetics, which hinder the enhancement of photocatalytic efficiency. In this context, two-dimensional (2D) materials known as MXenes have gained prominence. These materials exhibit unique structural flexibility, diverse elemental compositions, superior conductivity, excellent carrier mobility, and abundant active sites, making them valuable co-catalysts in photocatalysis. MXenes accelerate interfacial charge transfer kinetics and mitigate charge recombination, enhancing the overall photocatalytic performance. This review provides a comprehensive overview of various methods employed to prepare high-quality MXenes under different conditions, such as water solution etching, water-free etching, and other physical methods. It also explores diverse strategies for constructing MXene-based composite photocatalytic systems, including in situ growth synthesis, in situ oxidation synthesis, and electrostatic self-assembly. Additionally, the review discusses various MXenes-based photosystems, such as MXene/TiO2, MXene/CdS, MXene/g-C3N4, MXene/WO3, and BiOBr/MXene/MMTex, and their applications in photocatalytic processes, including hydrogen production, CO2 reduction, environmental remediation, nitrogen fixation, and sterilization. The critical role of MXenes as reduction co-catalysts in these photoredox catalysis reactions is thoroughly examined, along with an elucidation of the relationship between MXene electronic structure and charge transfer characteristics. Furthermore, the review addresses the challenges related to the stability of MXenes in photocatalytic reactions and offers insights into potential strategies to mitigate this issue. Finally, the development prospects and future challenges of MXene-based composites in the field of photocatalysis are presented, taking into consideration the inherent limitations of MXenes and the requirements for industrialization. It is expected that this review will provide valuable insights into the physicochemical properties of MXenes and inspire innovative approaches to the rational design of diverse MXene-based photosystems for heterogeneous photocatalysis across various applications. © Editorial office of Acta Physico-Chimica Sinica.

Abstract :

Wastewater pollutants are a major threat to natural resources, with antibiotics and heavy metals being common water contaminants. By harnessing clean, renewable solar energy, photocatalysis facilitates the synergistic removal of heavy metals and antibiotics. In this paper, MXene was both a template and raw material, and MXene-derived oxide (TiO2) and SnIn4S8 Z-scheme composite materials were synthesized and characterized. The synergistic mode of photocatalytic reduction and oxidation leads to the enhanced utilization of e(-)/h(+) pairs. The TiO2/SnIn4S8 exhibited a higher photocatalytic capacity for the simultaneous removal of tetracycline (TC) (20 mg center dot L-1) and Cr(VI) (15 mg center dot L-1). The main active substances of TC degradation and Cr(VI) reduction were identified via free radical scavengers and electron paramagnetic resonance (EPR). Additionally, the potential photocatalytic degradation route of TC was thoroughly elucidated through liquid chromatography-mass spectrometry (LC-MS).

Abstract :

Atomically precise metal nanoclusters (NCs) have been deemed as a new generation of metal nanomaterials because of their characteristic atomic stacking fashion, quantum confinement effect, and multitude of active sites. The discrete molecular-like energy band structure of metal NCs endows them with photosensitization capability for light harvesting and conversion. However, applications of metal NCs in photoelectrocatalysis are limited by the ultrafast charge recombination and unfavorable stability, impeding the construction of metal NC-based photosystems. In this work, we elaborately crafted multilayered metal oxide (MO)/(metal NCs/insulating polymer)(n) photoanodes by a facile layer-by-layer (LbL) assembly technique. In these well-defined heterostructured photoanodes, glutathione (GSH)-wrapped metal NCs (Ag-x@GSH, Ag-9@GSH(6), Ag-16@GSH(9), and Ag-31@GSH(19)) and an insulating poly(allylamine hydrochloride) (PAH) layer are alternately deposited on the MO substrate in a highly ordered integration mode. We found that photoelectrons of metal NCs can be tunneled into the MO substrate via the intermediate ultrathin insulating polymer layer by stimulating the tandem charge transfer route, thus facilitating charge separation and boosting photoelectrochemical water oxidation performances. Our work would open a new frontier for judiciously regulating directional charge transport over atomically precise metal NCs for solar-to-hydrogen conversion.

Abstract :

Fe -N -doped carbon materials (Fe -N -C) are promising candidates for oxygen reduction reaction (ORR) relative to Pt -based catalysts in proton exchange membrane fuel cells (PEMFCs). However, the intrinsic contributions of Fe -N4 moiety with different chemical/spin states (e.g. D1, D2, D3) to ORR are unclear since various states coexist inevitably. In the present work, Fe -N -C core-shell nanocatalyst with single lowspin Fe(II)-N4 species (D1) is synthesized and identified with ex -situ ultralow temperature M & ouml;ssbauer spectroscopy (T = 1.6 K) that could essentially differentiate various Fe -N4 states and invisible Fe -O species. By quantifying with CO -pulse chemisorption, site density and turnover frequency of Fe -N -C catalysts reach 2.4 x 1019 site g-1 and 23 e site -1 s-1 during the ORR, respectively. Half -wave potential (0.915 VRHE) of the Fe -N -C catalyst is more positive (approximately 54 mV) than that of Pt/C. Moreover, we observe that the performance of PEMFCs on Fe -N -C almost achieves the 2025 target of the US Department of Energy by demonstrating a current density of 1.037 A cm -2 combined with the peak power density of 0.685 W cm -2, suggesting the critical role of Fe(II)-N4 site (D1). After 500 h of running, PEMFCs still deliver a power density of 1.26 W cm -2 at 1.0 bar H2 -O2. An unexpected rate -determining step is figured out by isotopic labelling experiment and theoretical calculation. This work not only offers valuable insights regarding the intrinsic contribution of Fe -N4 with a single spin state to alkaline/acidic ORR, but also provides great opportunities for developing high-performance stable PEMFCs.

Abstract :

Wholly distinct from conjugated polymers which are featured by generic charge transfer capability stemming from a conjugated molecular structure, solid nonconjugated polymers mediated charge transport has long been deemed as theoretically impossible because of the deficiency of pi electrons along the molecular skeleton, thereby retarding their widespread applications in solar energy conversion. Herein, we first conceptually unveil that intact encapsulation of metal oxides (e.g., TiO2, WO3, Fe2O3, and ZnO) with an ultrathin nonconjugated polyelectrolyte of branched polyethylenimine (BPEI) can unexpectedly accelerate the unidirectional charge transfer to the active sites and foster the defect generation, which contributes to the boosted charge separation and prolonged charge lifetime, ultimately resulting in considerably improved photoelectrochemical (PEC) water oxidation activities. The interfacial charge transport origins endowed by BPEI adornment are elucidated, which include acting as a hole-withdrawing mediator, promoting vacancy generation, and stimulating the directional charge flow route. We additionally ascertain that such charge transport characteristics of BPEI are universal. This work would unlock the charge transfer capability of nonconjugated polymers for solar water oxidation. The nonconjugated insulating polymer was utilized as a charge transport mediator for boosting charge migration and separation over metal oxides toward solar water oxidation.

Abstract&Keyword Cite

Abstract :

Quantum dots (QDs) colloidal nanocrystals are attracting enduring interest by scientific communities for solar energy conversion due to generic physicochemical merits including substantial light absorption coefficient, quantum confinement effect, enriched catalytically active sites, and tunable electronic structure. However, photo-induced charge carriers of QDs suffer from ultra-short charge lifespan and poor stability, rendering controllable vectorial charge modulation and customizing robust and stable QDs artificial photosystems challenging. Herein, tailor-made oppositely charged transition metal chalcogenides quantum dots (TMCs QDs) and MXene quantum dots (MQDs) are judiciously harnessed as the building blocks for electrostatic layer-by-layer assembly buildup on the metal oxides (MOs) framework. In these exquisitely designed LbL assembles MOs/(TMCs QDs/MQDs)n heterostructured photoanodes, TMCs QDs layer acts as light-harvesting antennas, and MQDs layer serves as electron-capturing mediator to relay cascade electrons from TMCs QDs to the MOs substrate, thereby yielding the spatially ordered tandem charge transport chain and contributing to the significantly boosted charge separation over TMCs QDs and solar water oxidation efficiency of MOs/(TMCs QDs/MQDs)n photoanodes. The relationship between interface configuration and charge transfer characteristics is unambiguously unlocked, by which photoelectrochemical mechanism is elucidated. This work would provide inspiring ideas for precisely mediating interfacial charge transfer pathways over QDs toward solar energy conversion. Cascade charge transfer channel is elaborately designed over transition metal chalcogenides quantum dots via a facile layer-by-layer assembly strategy for significantly boosted solar water oxidation. image

Abstract :

The core factors dictating the photocatalysis efficiency are predominantly centered on controllable modulation of anisotropic spatial charge transfer/separation and regulating vectorial charge transport pathways. Nonetheless, the sluggish charge transport kinetics and incapacity of precisely tuning interfacial charge flow at the nanoscale level are still the primary dilemma. Herein, we conceptually demonstrate the elaborate design of a cascade charge transport chain over transition metal chalcogenide-insulating polymer-cocatalyst (TIC) photosystems via a progressive self-assembly strategy. The intermediate ultrathin non-conjugated insulating polymer layer, i.e., poly(diallyl-dimethylammonium chloride) (PDDA), functions as the interfacial electron relay medium, and simultaneously, outermost co-catalysts serve as the terminal "electron reservoirs", synergistically contributing to the charge transport cascade pathway and substantially boosting the interfacial charge separation. We found that the insulating polymer mediated unidirectional charge transfer cascade is universal for a large variety of metal or non-metal reducing co-catalysts (Au, Ag, Pt, Ni, Co, Cu, NiSe2, CoSe2, and CuSe). More intriguingly, such peculiar charge flow characteristics endow the self-assembled TIC photosystems with versatile visible-light-driven photoredox catalysis towards photocatalytic hydrogen generation, anaerobic selective organic transformation, and CO2-to-fuel conversion. Our work would provide new inspiration for smartly mediating spatial vectorial charge transport towards emerging solar energy conversion. The core factors dictating the photocatalysis efficiency are predominantly centered on controllable modulation of anisotropic spatial charge transfer/separation and regulating vectorial charge transport pathways.

Abstract :

Atomically precise metal nanoclusters (NCs) have been deemed a new generation of photosensitizers for light harvesting on account of their quantum confinement effect, peculiar atom-stacking mode, and enriched catalytic active sites. Nonetheless, to date, precise charge modulation over metal NCs has still been challenging considering their ultra-short carrier lifetime and poor stability. In this work, we conceptually demonstrate the integration of metal NCs with MXene in transition metal chalcogenide (TMC) photosystems via a progressive, exquisite, and elegant interface design to trigger tunable, precise and high-efficiency charge motion over metal NCs, stimulating a directional carrier transport pathway. In this customized ternary heterostructured photosystem, metal NCs function as light-harvesting antennas, MXene serves as a terminal electron reservoir, and the TMC substrate provides suitable energy level alignment for retracting photocarriers of metal NCs, giving rise to a spatial cascade charge transport route and markedly boosting charge separation efficiency. The interface configuration and energy level alignment engineering synergistically contribute to the considerably enhanced visible-light-driven photocatalytic CO2-to-CO reduction performance of the metal NCs/TMCs/MXene heterostructure. The intermediate active species during the photocatalytic CO2 reduction are unambiguously determined, based on which the photocatalytic mechanism is elucidated. Our work will provide an inspiring idea to bridge the gap between atomically precise metal NCs and MXene in terms of controllable charge migration for solar-to-fuel conversion. © 2024 The Royal Society of Chemistry.

绝缘聚合物调控光氧化还原催化的起源研究

Abstract :

固态非共轭聚合物由于缺乏沿分子链框架的离域π电子,长期以来被视为不具备转移能力的绝缘聚合物.因此,利用这类固态绝缘聚合物作为载体介质来刺激电荷转移或光氧化还原催化,在传统观念中被认为是不可行的.在异相光催化中,为了提升催化效率,常采用煅烧法去除非共轭绝缘聚合物,以暴露更多的活性位点,增强界面接触,从而减少界面电荷传输阻力并加速电荷转移.然而,由于聚合物的结构多样性和易获取性,深入探索非共轭绝缘聚合物在光催化中的电荷传输机制具有重要意义. 本文采用静电自组装策略,在常温下,将表面带负电荷的ZnIn2S4(ZIS)纳米片分散在带正电荷的固态绝缘支化聚乙烯亚胺(bPEI)的溶液中,通过两者间的静电作用力,制得具有高活性的、Zn空位调控的bPEI/ZIS光催化剂.X射线粉末衍射、拉曼光谱和紫外-可见漫反射光谱结果表明,bPEI的包覆并未改变ZIS的晶体结构和光学性质.高分辨透射电镜、原子力显微镜、X射线光电子能谱、傅里叶变换红外光谱和热重分析等结果证明了bPEI的成功包覆及显著的电子相互作用.采用瞬态吸收光谱、光致发光光谱、时间分辨光致发光光谱、光电流强度曲线和电化学阻抗曲线等光电化学测试,研究了催化剂的电荷传输路径和分离效率.电子顺磁共振谱和同步辐射吸收谱结果表明,采用15 mg mL-1的bPEI溶液包裹的ZIS(简称15bPEI/ZIS)中的Zn空位浓度显著高于ZIS,有利于延长载流子寿命.结合理论计算结果,推断bPEI的包裹可以优化Zn空位浓度,促进H2O和4-硝基苯胺的吸附.研究了析氧反应(OER)每步所需的自由能,结果表明,bPEI的存在有利于光生电子的转移.光催化还原硝基化合物性能评价结果表明,与ZIS相比,15bPEI/ZIS表现出更好的光催化活性和稳定性.在可见光下还原4-硝基苯胺体系中,15bPEI/ZIS的转化率可达91.58%,显著优于纯ZIS的16.33%.通过在体系中混合ZIS和bPEI制得15bPEI+ZIS,发现其光催化活性不如15bPEI/ZIS.同时,在惰性气氛下煅烧15bPEI/ZIS制得15bPEI/ZIS-200 ℃,相较于15bPEI/ZIS,15bPEI/ZIS-200 ℃的光催化性能没有显著提升,证明15bPEI/ZIS样品中ZIS和bPEI间界面结合紧密,存在强电子相互作用,有利于提升界面电荷传输效率.此外,在ZIS表面包裹多种含胺基的有机分子和聚合物催化剂,以及在ZIS和bPEI层间生长/刻蚀构建不同绝缘SiO2厚度的催化剂,通过光催化实验证实胺基官能团参与了界面电荷传输过程,并在光催化反应中抑制电荷复合并提供大量活性位点. 综上,本文从异相光催化的角度揭示了固态非共轭绝缘聚合物的电荷传输能力,并探讨了绝缘聚合物中单体片段对光催化性能的贡献作用.这种由绝缘聚合物包覆引起的协同缺陷工程、丰富的表面活性位点和加速的电荷流动动力学,共同显著提升了光催化活性.这一发现为利用固态绝缘聚合物操控电荷转移以实现太阳能转换提供新思路.

Abstract&Keyword Cite

Abstract :

Black phosphorus (BP), a promising two-dimensional (2D) layered semiconductor material, has gained enormous attention due to its impressive properties over the past several years. Although plenty of methods have been developed to synthesize high-quality BP, most of the currently available BP materials still suffer from unsatisfactory crystallization, purity, and stability in air, hindering their practical application. A facile approach to synthesizing ultrahigh-quality single-crystal BP is of significance to shed light on the nature of 2D semiconductor materials and their massive application. In this work, we present the facile and efficient circulating vapor growth approach to growing bulk single-crystal BP. The as-grown BP material features high crystallinity and ultrahigh purity (higher than 99.999 at %), exceeding those of all the previously reported and some commercially available BP crystals. It also maintains excellent stability in air and water after 15 consecutive days of test. Moreover, the as-synthesized BP material features good thermal stability, oxidation resistance, and excellent electrical properties, as well. This study provides a new approach for the fabrication of ultrahigh-quality BP material and thus promotes its application.
