中文摘要

开发高效绿色清洁能源已引起研究者们的广泛关注。电解水是一种大规模、可持续生产高纯氢能源技术。然而,阳极析氧反应电催化剂的高过电位和不稳定性制约了电解水技术的大规模应用,合理设计电催化剂的结构可显著优化其反应热力学和动力学,提高电解水技术的能量转换效率。表界面是电催化反应发生的主要场所,通过调控电催化剂表面的本征结构或构筑异质界面等系列表界面化学工程对电催化剂进行改性,可以有效改善材料的催化活性和稳定性。本文概述了当前表界面调控策略在电催化析氧反应中的研究进展,重点介绍了表界面调控层状双金属氢氧化物、钙钛矿型氧化物、尖晶石型化合物及合金材料的研究现状,阐述了高效稳定析氧反应电催化剂的设计思路。讨论了表界面调控策对催化剂表界面微结构和电子态的影响,以及设计新型析氧反应电催化剂中面临的问题。最后,展望了表界面调控应用于析氧反应电催化剂的前景。

Abstract

The increasing clean energy demands have promoted extensive attention on the development of alternative energy conversion technologies with high efficiency and green. Water splitting is a large-scale and sustainable technology for high-purity hydrogen production. However, the substantial overpotential and unsatisfied stability of oxygen evolution reaction (OER) electrocatalysts are great challenges for the widespread application of water splitting technology. Reasonal design of the structure of the OER electrocatalyst can significantly optimize its reaction thermodynamics and kinetics, thus improving the energy conversion efficiency of water splitting technology. The surface/interface is regarded as the main place where the electrocatalytic reaction occurs. The electrocatalysts, modified by surface/interface engineering, such as regulating intrinsic properties or designing synergistic interface, can improve their electrocatalytic efficiency and stability effectively. This review summarizes the application of surface/interface modulation strategies in OER, especially focusing on the research progress of layered double hydroxides, perovskite oxides, spinel compounds and alloy based materials. The design principles of high-efficient and stable electrocatalysts for OER are described. Based on the recent progress of surface/interface modulation applied in catalyst for OER,the effects of surface/interface modulation on the microstructure and electronic states of the catalyst are discussed．In addition, the challenges about modifications of above electrocatalysts are discussed. Finally, the opportunities of OER electrocatalysts via surface/interface modulation are prospected.
