Abstract: Water electrolysis by anodic oxygen evolving catalysis has drawn extensive attention in hydrogen production. Safe and efficient anodic oxygen catalyst is the key to realize the water splitting technology. Ag based catalysts are novel and promising oxygen evolving catalysts, as they can work under mild conditions and have lower oxygen evolution overpotential and modulated structures. Herein, Ag based oxygen-evolving catalysts in the application of water splitting for hydrogen production are presented. The methods of in situ modification such as matching electrolyte, controlling the concentration, pH, and temperature of electrolyte and modifying working electrode, and post-modification such as compositing metal oxidation, compositing graphene and controlling silver oxide nanocrystals, are reviewed. Besides, combining the two methods will provide some guidance and reference for further design of Ag based water oxidation catalyst.

Key words: Ag based, oxygen evolution catalyst, anode, electrolysis, oxidation, hydrogen production

摘要: 近年来基于阳极析氧催化的电解水制氢技术引起了广泛关注,安全、高效的阳极析氧催化剂是实现该技术的核心。银基析氧催化剂具有操作条件温和、析氧过电位低及结构易于调变的特性,是一种颇具发展前景的新型阳极析氧催化剂。本文综述了Ag基析氧催化剂的制备及其在电解水制氢方面的应用,着重介绍了Ag基析氧催化剂的两种调控改性方法,包括原位调控方法和后制备调控方法,其中原位调控方法主要有电解质溶液的匹配、电解质(浓度、酸碱度、温度)的调变和工作电极的修饰,后制备调控方法主要有金属氧化物复合、石墨烯复合和银氧化物纳米晶的调控。将原位调控和后制备调控相结合,可为制备具有较低过电势、较高催化活性的新型Ag基阳极析氧催化剂提供方法指导和为后续研究提供依据。
