Abstract ：
The utilization of H2S from industrial by-products as a hydrogen source offers an alternative approach for converting nitroarenes compounds (Ph-NO2) into aromatic amine (Ph-NH2) while also mitigating this environmental pollutant. However, the progress of this technology has been hindered by the lack of cost-effective and efficient catalysts. Herein, we present a porous K2MoSx/SiO2 catalyst synthesized using low-cost and environmentally friendly proline as template. The optimized K2MoSx/SiO2-proline catalyst achieves an 84 % conversion of Ph-NO2 with high Ph-NH2 selectivity for 91 % in the catalytic reduction of Ph-NO2 with H2S. Additionally, the K2MoSx/SiO2-proline shows considerable catalytic activity for the reduction of various substituted nitroarenes, demonstrating its versatility and broad applicability. The in situ DRIFTS and DFT calculations indicate that the reaction favors the formation of the essential intermediate *Ph-NO through a single H-induced pathway before proceeding to hydrogenation to yield Ph-NH2.

Abstract ：
The identification of novel and efficient piezoelectric catalysts is crucial for practical applications. Utilizing Density Functional Theory (DFT) calculations, ZnIn2S4 (ZIS), possessing a non-central symmetric crystal structure, is identified as a promising piezoelectric material for piezocatalysis. Hierarchical ZIS nanosheets are synthesized through a facile hydrothermal method, and defect engineering is employed to enhance their activity. By optimizing the defect concentration, ZIS-300, with the optimal defect level, demonstrates the highest H2 production rate of approximately 3164.67 mu mo1.g- 1.h- 1 under ultrasound, surpassing previously reported piezocatalysts. Furthermore, ZIS-300 exhibits good stability, maintaining its activity and structural integrity after five cycles. Detailed piezo-electrochemical analyses attribute the enhanced piezocatalytic performance to the introduction of sulfur vacancies, which create a shallow donor band facilitating the generation and separation of charge carrier. This work contributes to a deeper understanding of designing high-performance piezocatalysts through theoretical calculations and defect engineering strategies.

Abstract ：
Hydrogen sulfide (H2S), a secondary energy carrier with remarkable energy density, has emerged as an innovative hydrogen donor for the hydrogenation of nitroarenes. Nevertheless, the lack of efficient catalysts has impeded the development of this novel resource utilization method. Here, we proposed a facile and eco-friendly approach for the synthesis of isolated Cu sites on MXene catalysts by a combination of Lewis acid salt melt etching and oxidative dispersion. The as-designed MXene catalysts demonstrate high activity and product selectivity towards different nitroarenes at 70 degrees C within a 2 h reaction. The in-situ characterizations and DFT calculations reveal that the active Cu sites significantly lower the energy barriers for the nitro dissociation and hydrogenation of intermediates, facilitating amino formation. The mechanism involves an acceleration of the hydrogen transfer process over C6H5NO2*, leading to hydroxylation of the nitro group followed by deprotonation, ultimately resulting in the formation of an amino group.

Abstract ：
In recent years, piezo-catalytic hydrogen production has been widely investigated for potential applications. Despite various strategies having been utilized to enhance the performance of piezocatalysts, there is a scant report on improving catalytic activity through the modulation of carrier migration pathways. Herein, we have successfully synthesized BiOCl with exposed {001} and {010} facets through facet engineering. The built-in electric field within the BiOCl crystals is oriented perpendicular to the {001} facets and parallel to the {010} facets, leading to differing charge carrier transfer pathways in the two samples. Specifically, in the BiOCl-010 sample, due to the electric field parallel to the nanosheet plane, charge carriers migrate along the x-axis. In contrast, in the BiOCl-001 sample, the electric field is perpendicular to the nanosheet plane, causing charge carriers to transfer along the z-axis, resulting in a shorter charge carrier migration distance. Consequently, BiOCl-001 demonstrates superior piezo-catalytic performance compared to BiOCl-010 toward H2 production and dye degradation. Both samples exhibit identical morphologies and similar energy band structures. Therefore, the enhanced performance is attributed to its shorter charge transport distance as well as the relatively higher piezoelectric coefficient associated with the {001} facets of BiOCl, which facilitates effective carrier separation.

Abstract ：
Photocatalytic N2 reduction using H2O to produce NH3 offers a promising alternative to the energy-intensive Haber-Bosch process. Nevertheless, its efficiency is hampered by the low solubility of N2 in water, the high stability of N---N and the competing H2 evolution reaction (HER). In this study, we present a highly efficient nanohybrid system employing BiOBr nanoflowers with O defect as a platform for anchoring Ru. The designed nanohybrids exhibit a significantly higher NH3 generation rate of 121.97 mu mol g-1 h-1, which is 6.1 and 2.8 times higher than that of pristine BiOBr-NS and Ru modified BiOBr without O defect, respectively. Experimental analyses and theoretical calculations reveal that the nanoflower structure with confined nano-space promotes the enrichment of N2 on the catalyst, the synergistic O defects and Ru facilitate the selective adsorption and activation of N2 and lower the energy barriers of the rate-determining *N-N to *N-NH step.

Abstract ：
Simultaneous H2 production and benzyl alcohol oxidation is an effective strategy for fully utilizing photoexcited electrons and holes of the photocatalysts. Herein, PtO are decorated on hollow CdS microspheres to fabricate a coupling photocatalytic system for accelerating H2 generation and selective oxidation of benzyl alcohol to benzaldehyde. The PtO-CdS hollow microspheres have been prepared by a facile hydrothermal method without any template agents. Under simulated sunlight irradiation, the 1 %PtO/CdS exhibited the highest rates of H2 evolution and benzaldehyde production. In addition, the PtO-CdS photoctalyst is stable during five cycles of photocatalytic reaction. Photoelectrochemical analyses coupled with ESR measurement demonstrated that PtO decoration not only promotes the charge separation but also improves the stability of the CdS. It is hoped that this work would provide useful information for the synthesis of CdS nanostructure for target application.

Abstract ：
Reasonable adjustment of the exposed crystal facets has been proven to be an effective strategy to improve the activity of the catalyst. However, the crystal-facet-dependent piezoactivity is rarely investigated. In this work, BiFeO3 with highly exposed (012) or (110) crystal facets were synthesized by adjusting the volume ratio of solvent and reaction time. Ethylene glycol was used as a structure-directing agent for the synthesis of BiFeO3 nanosheets (BiFeO3-NS) with highly exposed (012) facets. BiFeO3-NS shows an obvious higher piezoelectric catalytic hydrogen evolution rate than that of BiFeO3 nanoparticles (BiFeO3-NP) with highly exposed (110) facets. In addition, the rate constant of BiFeO3-NS for the piezocatalytic degradation of rhodamine B (RhB) shows a 2-fold increase than that of BiFeO3-NP. A variety of controlled experiments have been performed. It is revealed that these two nanomaterials exhibit comparable specific surface areas and adsorption capacity. BiFeO3-NS possesses narrowed bandgap as compared to that of BiFeO3-NP. The enhanced piezocatalytic activity of BiFeO3-NS can be attributed to its built-in electric field, strong carrier mobility, and effective charge separation efficiency. This study provides an alternative perspective for piezoelectric catalysis in surface engineering.

Abstract ：
Electrocatalytic nitrate reduction reaction (NO3RR) has been capturing immense interest in the industrial application of ammonia synthesis, and it involves complex reaction routes accompanied by multi-electron transfer, thus causing a challenge to achieve high efficiency for catalysts. Herein, we customized the Cu-O-Ti-Ov (oxygen vacancy) structure on the Cu/TiO2 catalyst, identified through density functional theory (DFT) calculations as the synergic active site for NO3RR. It is found that Cu-O-Ti-Ov site facilitates the adsorption/association of NOx- and promotes the hydrogenation of NO3- to NH3 via adsorbed *H species. This effectively suppresses the competing hydrogen evolution reaction (HER) and exhibits a lower reaction energy barrier for NO3RR, with the reaction pathways: NO3* -> NO2* -> HONO* -> NO* -> *NOH -> *N -> *NH -> *NH2 -> *NH3 -> NH3. The optimized Cu/TiO2 catalyst with rich Cu-O-Ti-Ov sites achieves an NH3 yield rate of 3046.5 mu g h-1 mgcat-1 at -1.0 V vs. RHE, outperforming most of the reported activities. Furthermore, the construction of Cu-O-Ti-Ov sites significantly mitigates the leaching of Cu species, enhancing the stability of the Cu/TiO2 catalyst. Additionally, a mechanistic study, using in situ characterizations and various comparative experiments, further confirms the strong synergy between Cu, Ti, and Ov sites, which is consistent with previous DFT calculations. This study provides a new strategy for designing efficient and stable electrocatalysts in the field of ammonia synthesis. Published by Elsevier B.V. All rights reserved.

Abstract ：
Various exposed facets can cause a huge difference in the catalytic activity. Here we prepared Co3O4 hexagonal nanosheets with exposed {112}, {112}&{111}, and {111} facets for the electrochemical nitrate reduction reactions (NO3RR). The reaction pathways of the NO3RR on Co3O4 {111} and {112} facets are clarified through in situ electrochemical characterizations and theoretical analysis. As the dominating facet of Co3O4 transforms from {112} to {111}, the rate-determining step changes from *NO2 -> *NO2H to *NO3H -> *NO2, with the energy barrier decreasing to 0.48 eV. And the {111} facet promotes the hydrogenation of NOx and NHx intermediates. Notably, the Co3O4-{111} catalyst shows exceptional NO3RR performance, achieving an NH3 yield of 5.73 mg mg(cat.)(-1) h(-1), surpassing the majority of the reported activities.

Abstract ：
Electrocatalytic depolymerization of lignin into value-added chemicals offers a promising technique to make biorefining sustainable.Herein,we report a robust trimetallic PdNiBi electrocatalyst for reductive C-O bond cleavage of different lignin model dimers and oxidized lignin under mild conditions.The reduction reaction proceeds with complete substrate conversion and excellent yields toward monomers of phenols(80％-99％)and acetophenones(75％-96％)in the presence of an ionic liquid electrolyte with operational stability.Systematic experimental investigations together with density functional theory(DFT)calculations reveal that the outstanding performance of the catalyst results from the synergistic effect of the metal elements,which facilitates the easier formation of a key Cα radical intermediate and the facile desorption of the as-formed products at the electrode.The results open up new opportunities for lignin valorization through the green electrocatalytic approach.
