Abstract ：
Molybdenum phosphide (MoP) is recognized as one of the most promising catalysts for the hydrogen evolution reaction (HER); however the low electronic conductivity and complicated synthesis process still restrict its commercialization as a replacement for the benchmark Pt/C catalyst. Herein, a novel type of MoP nanoparticles encapsulated with biomolecule-derived N, P-codoped carbon nanosheets has been successfully fabricated by a simple one-step pyrolysis of ammonium molybdate tetrahydrate, 1-hydroxyethylidene diphosphonic acid (HEDP) and a unique biomolecule guanine as the precursor of two-dimensional carbon materials. Benefiting from the well-designed architecture with both good electronic conductivity and easily accessible catalytic sites provided by the 2D carbon structure, the optimized catalyst exhibits synergistically enhanced HER activity under both alkaline and acidic conditions, especially with a low overpotential of 104 mV to deliver 10 mA cm-2 in 1 M KOH. Moreover, the coverage of N, P-codoped graphene-like carbon layers can prevent the corrosion of MoP nanoparticles in harsh reaction media, ensuring superior durability. This work has opened up a new direction for further development of simple, low-cost but efficient novel electrocatalysts. A one-step pyrolysis strategy to synthesize novel MoP nanoparticles encapsulated with biomolecule-derived N, P-codoped carbon nanosheets for synergistic hydrogen evolution reaction.

Abstract ：
Maximization the synergistic effect of each component in transition metal-carbon complexes is expected to improve the bifunctional oxygen electrocatalysis for rechargeable Zn-air batteries but is still challenging. Herein, nucleobase guanine is employed as a supramolecular precursor to generate the core (FeCo alloy)-shell (carbon) structure embedded in ultrathin graphene-like nitrogen-doped carbon nanosheets (FeCo@NCNSs) via a confinement pyrolysis strategy. Thanks to the generated core-shell structure and bimetallic synergistic effect, the as-prepared FeCo@NCNSs exhibits excellent electrochemical performance in both oxygen reduction reaction and oxygen evolution reaction. As a result, when served as the bifunctional air electrode for a practical Zn-air battery, FeCo@NCNSs exhibits a higher open-circuit voltage (1.553 V) and peak power density (197.30 mW cm-2), as well as the greatly improved long-term cyclic stability compared to the noble metal benchmarks. This work provides a promising approach to integrate various active sites for bifunctional oxygen electrocatalysis and inspires the exploration of simple but efficient electrocatalysts for energy storage and conversion.

Abstract ：
Iron-nitrogen-carbon (Fe-N-C) catalyst has emerged as highly promising contender for oxygen reduction reaction (ORR), yet challenges such as limited active site accessibility and intricate synthesis procedures impede their commercialization as a replacement for the benchmark Pt/C catalyst. Herein, we present an innovative approach to in situ fabricate a unique iron and nitrogen co-doped 3D porous carbon material. The material is synthesized through a straightforward one-step pyrolysis of xanthine, oxidized carbon nanotubes and iron nitrate nonahydrate mixture. During the high temperature pyrolysis, the nucleobase xanthine undergoes gradually transformation into an efficient N-doped graphene-like material. Simultaneously, it assembles with carbon nanotubes (CNTs), resulting in the formation of a unique 3D graphene-CNTs composite structure composed of graphene and CNTs. This exceptional 3D porous structure serves as an excellent scaffold, ensuring firm anchoring, uniform dispersion, and optimal exposure of numerous FeNx active sites. Leveraging this well-engineered framework, the optimized Fe-N-C catalyst (NC/CNT/Fe0.04) shows excellent ORR performance with an onset potential of 1.03 V vs. RHE, a half-wave potential of 0.87 V vs. RHE, and a diffusion-limited current density of −5.59 mA cm−2, even better than those of the commercial Pt/C catalyst. This work provides valuable insights into the design of efficient electrocatalysts with 3D channel. © 2024 Elsevier Ltd

Abstract ：
As a sort of fluorescent carbon nanomaterial with a particle size of less than 10 nm, carbon dots (CDs) have their own merits of good dispersibility in water, stable optical properties, strong chemical inertness, stable optical properties, and good biosecurity. These excellent peculiarities facilitated them like sensing, imaging, medicine, catalysis, and optoelectronics, making them a new star in the field of nanotechnology. In particular, the development of CDs in the fields of chemical probes, imaging, cancer therapy, antibacterial and drug delivery has become a hot topic in current research. Although the biomedical applications in CDs have been demonstrated in many research articles, a systematic summary of their role in biomedical applications is scarce. In this review, we introduced the basic information of CDs in detail, including synthesis approaches of CDs as well as their favorable properties including photoluminescence and low cytotoxicity. Subsequently, the application of CDs in the field of biomedicine was emphasized. Finally, the main challenges and research prospects of CDs in this field were proposed, which might provide some detailed information in designing new CDs in this promising biomedical field. © 2023

Abstract ：
Biomass derived small molecules are sustainable feedstocks to synthesize high value-added products. Herein, we demonstrate a facile one-pot hydrothermal method to fabricate a molybdenum sulfide modified nickel-based catalyst for the electrochemical oxidation of HMF to 2,5-furandicarboxylic acid (FDCA). The as-synthesized catalyst shows a unique nano-flower-like microstructure with features of a large surface area, excellent conductivity and high-valence Mo species. Electrochemical tests indicate that the onset potential increases to 1.27 V after the addition of HMF, which is much lower than that of water oxidation. This change suggests that the oxidation of HMF occurs before the slow kinetic oxygen evolution reaction (OER), potentially acting as an alternative to the OER cathodic reaction to drive hydrogen evolution and CO2 reduction. Moreover, the reaction achieves 100% conversion and 99% selectivity, which is because molybdenum sulfide accelerates the in situ oxidation of Ni2+ to NiOOH and Ni3+. This study provides a new pathway for the conversion of HMF into FDCA, a promising substitute for the petroleum derivative terephthalic acid.

Abstract ：
Natural nitrogen-heterocycles biomolecules have been widely used in the construction of supramolecular selfassemblies due to their abundant resources and multiple interaction sites, such as hydrogen bonding, pi-pi stacking, van der Waals forces. Herein, we propose a quite innovative strategy to produce two-dimensional (2D) carbon materials by direct pyrolysis of various nucleobases (e.g. guanine, adenine, uracil, cytosine xanthine, and hypoxanthine). These nucleobases can pre-organize a planar network structure through hydrogen bonding interaction. The multiple hydrogen-bonding can be stable at relatively high temperature, which limits C-C or C-N cleavage and formation in a 2D space. These 2D carbons show desirable features with highly sp2-conjugation, tunable heteroatom contents, and ultrathin thickness, without the need of any template or additional purification. Meanwhile, differences in internal structure allow easy control of the morphology of 2D carbons, porosity and surface chemical functionality at the molecular level. Moreover, the as-synthesized 2D carbons display very promising electrocatalytic ORR performance and catalytic performance for selective oxidization of ethylbenzene. Given the diversity in the structure of the nucleobase moiety, they represent ideal building blocks for the catalyst-free and metal-free formation of 2D carbon architectures.

Abstract ：
Two-dimensional (2D) carbon materials with ultrathin thickness, large lateral size, large surface area, accessible active sites and unique physical-chemical properties have been proven to be attractive electrode materials or catalysts for high-efficient energy storage and conversion materials. However, the conventional synthesis method for 2D carbon materials heavily depends on fossil-based feedstocks and goes through harsh conditions (e.g., chemical vapor deposition), which are unsustainable and costly. Besides, the top-down method needs to use massive strong acids/oxidants, which is environmentally-unfriendly. Therefore, it is necessary to commit to seek green, sustainable and cost-effective approach for the synthesis of 2D carbon materials. As of now, biomass or biological molecules as carbon-rich resources have been viewed as a promising candidate for the 2D carbon material preparation owing to its abundance, renewability, nontoxicity and low-cost. Especially for nucleobases, as an emerging molecule have been shown great advantages for the construction of 2D materials guided by its multiple hydrogen-bonding interaction. Recently, our group have proposed a rather innovative strategy to produce 2D carbon materials by carbonization of nucleobases which has relatively high electrode potentials. These nucleobases can form planar network structure through hydrogen bonding interaction. Such hydrogenbonding can be stable at relatively high temperature, which confines C-C or C-N polymerization in a 2D plane. As a result, direct carbonization of nucleobases enables the formation of 2D carbon with highly sp2-conjugated and feature of heteroatom doping. This review systematically summarizes the recent development of the strategies to synthesize 2D sustainable carbon materials from biomass and biological molecules. The corresponding electrochemical applications such as lithium ion batteries, supercapacitors and fuel cell are selectively presented. At the end, the summary and future perspectives in this important field are provided to inspire further exploration.

Abstract ：
Electrochemical water splitting to produce hydrogen is a key technology for converting sustainable energy into chemical fuels. The high overpotential and sluggish kinetics for the electrocatalytic hydrogen evolution reaction (HER) lead to low energy conversion efficiency. Herein, we report a new electrocatalyst of RuCu supported on guanine-derived carbon nanosheets for highly efficient HER, in which the trace Cu of 0.1 wt% loadings can significantly boost the electrocatalytic activity during the whole pH range. Specifically, the 0.5Ru0.1Cu-GN1000 can release a current density of 10 mA/cm(2) at 68 mV and 157 mV in 1.0 M KOH and 0.5 MH2SO4, respectively. This catalyst still delivers a high HER activity even in the actual seawater. The improvement of HER activity can be ascribed to the strong interaction between Ru and Cu, resulting in the formation of an electron-rich state of Ru nanoparticles at the surface for series of HER at low overpotential. This research has opened up a promising pathway towards electrocatalytic water splitting through the innovation of carbon support and the modulation of metal interactions.

Abstract ：
Fabricating of high performance electrodes by a sustainable and cost effective method is essential to the development of vanadium redox flow batteries (VRFBs). In this work, an effective strategy is proposed to deposit carbon nanoparticles on graphite felts by hydrothermal carbonization method. This in-situ method minimizes the drop offand aggregation of carbon nanoparticles during electrochemical testing. Such integration of felts and hydrothermal carbons (HTC) produces a new electrode that combines the outstanding electrical conductivity of felts with the effective redox active sites provided by the HTC coating layer. The presence of the amorphous carbon layers on the felts is found to be able to promote the mass/charge transfer, and create oxygenated/nitrogenated active sites and hence enhances wettability. Consequently, the most optimized electrode based on a rational approach delivers an impressive electrochemical performance toward VRFBs in wide range of current densities from 200 to 500 mA cm(-2). The voltage efficiency (VE) of GFs-HTC is much higher than the VEs of the pristine GFs, especially at high current densities. It exhibits a 4.18 times increase in discharge capacity over the pristine graphite felt respectively, at a high current density of 400 mA cm(-2). The enhanced performance is attributed to the abundant active sites from amorphous hydrothermal carbon, which facilitates the fast electrochemical kinetics of vanadium redox reactions. This work evidences that the glucose-derived hydrothermal carbons as energy storage booster hold great promise in practical VRFBs application.

Abstract ：
Selective oxidation of aromatic alkanes by C-H activation is one of the key reactions in organic synthesis and the chemical industry. Activation of C-H bonds to obtain high-value added products under mild conditions by using sustainable carbocatalysts is of particular interest. Herein, we report a sustainable, green and template-free strategy towards the fabrication of N-doped and N/S codoped carbon nanosheets by metal-free carbonization of bioprecursors guanine and guanine sulfate. The formation of thin and N/S codoped carbon nanosheets was induced by multiple interactions of the nucleobases. Benefiting from the unique textural structure of the as-synthesized carbons, including ultrathin thickness, optimal porosity, and rich structural defects, and the synergistic coupling effect of multiple dopants, the carbon nanosheets show a high catalytic performance with 85% ethylbenzene conversion and 98% selectivity to acetophenone at 80 degrees C after 4 h reaction, which outperforms other equivalent benchmarks (e.g. 8.5 times higher conversion and 3.2 times higher selectivity than those of oxidized carbon nanotubes). Density functional theory simulations indicate that the oxidation of ethylbenzene is catalyzed by the synergistic effect of p-N/S and g-N/S catalysts via an OH radical mechanism. This N/S codoped strategy provides guidance for the design of carbon-based catalysts for the selective oxidation of other alkanes.
