It makes those electrochemical reactions with multiple electron-proton transfers more complex when determining kinetics and mass transfer information. Understanding how HER competes with other electrochemical reduction reactions is crucial for both fundamental studies and system performance improvements. In this study, we employed the oxygen reduction reaction (ORR) as a model reaction to investigate HER competition on a polycrystalline-Au surface, using a rotating ring and disk electrode. It’s proved that water molecules serve as the proton source for ORR in alkaline, neutral, and even acidic electrolytes, and a 4-electron process can be achieved when the overpotential is sufficiently high. The competition from H⁺ reduction becomes noticeable at the H⁺ concentration higher than 2 mmol L^–1 and intensifies as the H⁺ concentration increases. Based on the electrochemical results, we obtained an equivalent circuit diagram for the ORR system with competition from the H⁺ reduction reaction, showing that these reactions occur in parallel and compete with each other. Electrochemical impedance spectroscopy measurements further confirm this argument. Additionally, we discover that the contribution of H⁺ mass transfer to the total H⁺ reduction current is significant and comparable to the kinetic current. We believe this work will deepen our understanding of HER and its competition in electrochemical reduction systems.</div></div>","PeriodicalId":9832,"journal":{"name":"Chinese Journal of Catalysis","volume":"73 ","pages":"Pages 271-278"},"PeriodicalIF":15.7,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144572962","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we propose a novel method to modulate metal nanoparticle size within Schottky junctions by controlling light intensity during the photodeposition process. Smaller Au nanoparticles were found to enhance electron accumulation at active sites by promoting charge transfer from COF to Au, thereby improving internal electron transport. Additionally, the Schottky barrier effectively suppressed reverse electron transfer while enhancing NO₃^– adsorption and activation. The Au₂-COF exhibited remarkable nitrate reduction performance, achieving an ammonia yield of 382.48 μmol g^–1 h^–1, 5.7 times higher than that of pure COF.

However, the production of H₂O₂ primarily relies on the anthraquinone method, which is an energy-intensive method involving multi-step reactions, producing harmful by-product wastes. Solar-driven H₂O₂ production, an alternative route for H₂O₂ generation, is a green and sustainable technology since it only utilizes water and oxygen as feedstock. However, the rapid recombination of charge carriers as well as insufficient redox capability limit the photocatalytic H₂O₂ production performance. Constructing step-scheme (S-scheme) heterojunction photocatalysts has been regarded as an effective strategy to address these drawbacks because it not only achieves spatially separated charge carriers, but also preserves redox capability of the photocatalytic system. This paper covers the recent advances of S-scheme heterojunction photocatalysts for H₂O₂ production in terms of basic principles, characterization techniques, and preparation strategies. Moreover, the mechanism and advantages of S-scheme heterojunction for photocatalytic H₂O₂ generation are systematically discussed. The recent S-scheme heterojunction designs, including inorganic-organic heterojunction, inorganic-inorganic heterojunction, and organic-organic heterojunction, are summarized.

For sustainable methanol synthesis, In₂O₃ is an ideal catalyst and has garnered significant attention. Herein, cubic In₂O₃ nanoparticles were prepared via the precipitation method and evaluated for CO₂ hydrogenation to produce methanol. During the initial 10 h of reaction, CO₂ conversion gradually increased, accompanied by a slow decrease of methanol selectivity, and the reaction reached equilibrium after 10-20 h on stream. This activation and induction stage may be attributed to the sintering of In₂O₃ nanoparticles and the creation of more oxygen vacancies on In₂O₃ surfaces. Further experimental studies demonstrate that hydrogen induction created additional oxygen vacancies during the catalyst activation stage, enhancing the performance of In₂O₃ catalyst for CO₂ hydrogenation. Density functional theory calculations and microkinetic simulations further demonstrated that surfaces with higher oxygen vacancy coverages or hydroxylated surfaces formed during this induction period can enhance the reaction rate and increase the CO₂ conversion. However, they predominantly promote the formation of CO instead of methanol, leading to reduced methanol selectivity. These predictions align well with the above-mentioned experimental observations.
