过渡金属钴酸盐电催化剂的研究进展
Research progress of transition metal cobaltate electrocatalysts
摘要
Abstract
In the process of hydrogen production via water electrolysis,the slow kinetics and high overpotential of the oxygen evolution reaction result in considerable energy consumption.Therefore,developing efficient,stable,and low-cost non-noble metal electrocatalysts is of great significance.Cobaltates are regarded as a promising alternative to noble-metal catalysts,owing to their excellent electron transfer capability derived from the multivalent nature of cobalt ions,as well as their rich and tunable crystal structures,such as spinel,perovskite,and layered frameworks.This paper systematically elaborates on the structure-activity relationships among the crystal structure,classification,and surface properties of cobaltates and their electrocatalytic performance.It summarizes mainstream synthesis methods,including solid-state,sol-gel,and hydrothermal/solvothermal routes.Furthermore,it provides an in-depth analysis of the mechanisms and effectiveness of surface engineering strategies,such as morphology control,heteroatom doping,and defect engineering,in enhancing the electrocatalytic performance of cobaltates.Finally,the challenges and future prospects of cobaltates as electrocatalysts are discussed,focusing on key issues such as improving stability,enhancing catalytic activity,and further investigating the underlying mechanisms.关键词
