Abstract ：
MXene quantum dots (QDs) possess the electron-withdrawing capability of MXene nanosheets (NSs) with more abundant active sites, rendering it an emerging charge mediator for photocatalysis. Nevertheless, few MXene QD-based photocatalytic systems have been explored, and the contribution of MXene QDs for the modulation of charge transfer remains elusive. Herein, we show the construction of cascade charge flow over transition metal chalcogenides (TMCs), which are coated via a polyelectrolyte layer of poly(dialyldimethylammonium chloride) (PDDA), followed by MXene QD deposition. It was unleashed that the intermediate PDDA layer serves as a charge relay medium to boost the electron transfer from TMC NSs to MXene QDs, boosting the charge transfer kinetics, promoting the interfacial charge separation, and endowing the TMCs@PDDA-M QD heterostructures with considerably enhanced visible-light-driven photoactivities for reduction of aromatic nitro compounds.

Abstract ：
Atomically precise metal nanoclusters (NCs), distinguished by their unique electronic structures, quantum confinement effects, and enriched active sites, have been considered highly promising photosensitizers for light harvesting and conversion. However, the ultra-short carrier lifetime and poor stability of metal NCs remarkably retard their widespread applications in photocatalysis. In this study, we achieved the modulation of carrier separation over metal NCs via heterostructure engineering by smartly integrating atomically precise silver NCs [Ag16(GSH)9] with transition metal chalcogenides (TMCs). The favorable energy level alignment between metal NCs and TMCs facilitates the electron transfer from the metal NCs to the TMCs, leading to a significantly prolonged charge lifetime and considerably enhanced photoactivity toward the selective reduction of nitro compounds to amino derivatives under visible light. The photocatalytic mechanism of these composite photosystems is elucidated herein. This work advances our fundamental understanding of charge transfer mechanisms over atomically precise metal NCs for solar energy conversion. © 2024 The Royal Society of Chemistry.

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 ：
Background: The accumulation of antibiotics in water systems has received considerable global attention due to its detrimental effects. There is an urgent need to develop rapid and efficient methods for the degradation of antibiotics.Methods: In this work, a highly efficient AgFeO2/Ag3VO4 photocatalyst was successfully fabricated by a hydrothermal method and analyzed using different techniques. Under visible light irradiation, photocatalytic behavior of AgFeO2/Ag3VO4 heterojunctions in the degradation of levofloxacin is investigated. Significant findings: The results showed that p-n heterojunction was formed between AgFeO2 and Ag3VO4, which improved the separation and transfer of photogenerated charge carrier under the action of the internal electric field. The apparent reaction rate of AgFeO2/Ag3VO4 heterostructure toward degradation of levofloxacin reached to 0.2770 min-1, which was about 2.15 times and 36.73 times larger than those of Ag3VO4 and AgFeO2, respectively, and much larger than other counterparts. Furthermore, possible photocatalytic degradation pathway of levofloxacin was comprehensively determined by LC-MS analysis. This work would provide in-depth understanding on the efficient photocatalytic removal of antibiotics for sustainable environmental remediation.

Abstract ：
Metal oxides (MOs)-based photoelectrochemical (PEC) cell, as an environmentally friendly and sustainable technique to convert solar energy to chemical energy, has been attracting enduring interest in the past few decades. However, sluggish charge transport dynamics, tough vectorial controllable charge migration route, and confined light absorption of MOs retard the solar energy conversion efficiencies of MOs-based photoelectrodes. Apart from MOs, transition metal chalcogenides (TMCs) photoanodes directly growing on the conductive substrate for PEC water splitting have been so far rarely reported albeit their generic merits of large absorption coefficient, suitable energy level alignment, and abundant active sites. Herein, we conceptually demonstrate the tunable construction of homogeneous TMCs heterostructured photoanodes (In2S3-CdIn2S4, In2S3-ZnIn2S4) by a facile, easily accessible, simple yet efficient cation exchange strategy at ambient conditions. The thus-designed TMCs composite photoanodes demonstrate significantly enhanced PEC water splitting performances relative to the pristine counterparts under both visible and simulated solar light irradiation, which is predominantly attributed to the markedly improved interfacial charge transfer/separation afforded by the favorable energy level configuration between the TMCs substrate and newly formed TMCs phase. We additionally ascertain that such ion exchange approach is universal for crafting other TMCs-based hybrid photoanodes. Our work is expected to provide an emerging avenue to craft a large variety of TMCs-based heterostructured photoanodes for solar energy conversion.

Abstract ：
Precisely modulating the spatial charge migration/separation constitutes the central issue in dictating the solar conversion efficiency of photoelectrochemical (PEC) cells, whereas it still remains a grand challenge. Here, we conceptually demonstrate the construction of hierarchically ordered metal oxide (MO)/transition-metal chalcogenide quantum dots (TMC QDs) multilayered heterostructured photoanodes, that is, MO/[TMC QDs(+)/TMC QDs(-)](n) (TMC QDs: CdTe, CdSe, CdS), by a simple and general bottom-up self-assembly route. Tailor-made intrinsically oppositely charged TMC QDs are alternately deposited on the highly ordered MO via a generic ligand-triggered electrostatic interaction to craft heterostructured photoanodes. The charge-transfer pathway stimulated by the photosensitization of TMC QDs is finely tuned by the assembly sequence. The advantageous multilayered nanoarchitecture renders the MO/[TMC QDs(+)/TMC QDs(-)](n) photoanodes exhibit substantially enhanced PEC performances under light irradiation, owing to the applicable energy-level configuration and peculiar combination fashion between building blocks and considerably boosted interfacial charge separation resulting from generating spatial tandem charge transport. Furthermore, photosensitization efficiency comparison among TMC QDs is comprehensively performed with PEC mechanisms elucidated.

Abstract ：
Transition metal chalcogenides quantum dots (TMCs QDs) demonstrate emerging potential in solar energy conversion owing to marvelous physicochemical properties, such as quantum size effect, large extinction coefficient, and multiple excitons generation. Nevertheless, TMCs QDs as photosensitizers are unstable owing to high surface energy, and moreover, substantial trap states of TMCs QDs annihilate the photo-induced charge carriers, thus resulting in ultra-short charge lifetime and inferior photoactivities. Herein, 0D/2D TMCs QDs/MXene heterostructures were designed by a ligand-initiated electrostatic self-assembly strategy, wherein positively charged TMCs QDs were anchored on the negatively charged ultrathin Ti3C2Tx nanosheets (NSs) framework, which promotes the anisotropic unidirectional electron transport from TMCs QDs to MXene NSs. MXene functions as an effective charge mediator to decrease the charge recombination and prolong the charge lifetime for photocatalytic hydrogen generation and anaerobic reduction of nitroaromatics to amino compounds under visible light irradiation. Our work would shed new insights on the role of MXene in tuning the directional charge transport for solar energy conversion. (C) 2021 Elsevier Inc. All rights reserved.
