摘要:

利用两电子路径的电化学氧还原反应来合成过氧化氢已成为一种极具潜力和低碳新型化工技术。过去的研究和成果主要致力于开发新型的碳基电催化剂。然而,碳基催化材料的合成过程复杂、高电位选择性不稳定且活性位点不明确等问题一直被广泛诟病。基于此,催化稳定性较高且材料微结构调控性较好的过渡金属氧化物和硫属化合物在两电子氧还原上的应用开始加速涌现。因此,本综述对此类材料用于氧气-过氧化氢电化学转换的金属氧化物和硫属化合物发展进行前瞻性讨论。首先,针对其多样性和催化活性,从实验合成和理论模拟的角度进行综述。同时,根据其形貌、相组成、掺杂和缺陷调控,对氧化物和硫属化合物的拓扑结构和化学特性与两电子选择性的潜在关系进行剖析。进而,对金属氧化物和硫属化合物的活性位点和反应机理等相关研究进展进行了讨论和总结。最后,对过渡金属氧化物和硫属化合物在两电子氧还原制取过氧化氢上的应用挑战和前景进行了分析,并提出了相关的建议。本综述提供了金属氧化物/硫属化合物在两电子氧还原上的基础研究及分析,以推动其在能源相关产业上的实际应用。

Abstract:

Electrochemical oxygen reduction reaction via the two-electron pathway (2e-ORR) is becoming a promising and sustainable approach to producing hydrogen peroxide (H2O2) without significant carbon footprints. To achieve better performance, most of the recent progress and investigations have focused on developing novel carbon-based electrocatalysts. Nevertheless, the sophisticated preparations, decreased selectivity and undefined active sites of carbon-based catalysts have been generally acknowledged and criticized. To this end, transition metal oxides and chalcogenides have increasingly emerged for 2e-ORR, due to their catalytic stability and tunable microstructure. Here, the development of metal oxides and chalcogenides for O2-to-H2O2 conversion is prospectively reviewed. By summarizing previous theoretical and experimental efforts, their diversity and outstanding catalytic activity are firstly provided. Meanwhile, the topological and chemical factors influencing 2e-ORR selectivity of the metal oxides/chalcogenides are systematically elucidated, including morphology, phase structures, doping and defects engineering. Thus, emphasizing the influence on the binding of ORR intermediates, the active sites and the underlying mechanism is highlighted. Finally, future opportunities and challenges in designing metal oxides/chalcogenides-based catalysts for H2O2 electro-synthesis are outlined. The present review provides insights and fundamentals of metal oxides/chalcogenides as 2e-ORR catalysts, promoting their practical application in the energy-related industry.
