摘　　要：总结了近年来基于不同第一过渡系列金属的分子水氧化催化剂,包括贵金属分子水氧化催化剂和非金属分子水氧化催化剂;以及常用的氧化物半导体电极材料,例如α-Fe2O3、WO3和BiVO4等。概述了目前分子水氧化催化剂在电极表面的负载方式,包括物理吸附方式、共价键结合方式、分子催化剂修饰吸附基团方式、静电作用和π-π堆积作用等。提出构建高效稳定的光致水分解分子器件需要解决的问题,从而实现利用太阳能大规模裂解水制备清洁能源的设想。Utilizing sunlight to split water into hydrogen and oxygen is an ideal way to convert solar energy into chemical energy and solve energy and environmental problems. In general, water splitting is hindered by the oxidation of water to oxygen which involves transfer processes of four electrons and four protons. To overcome this obstacle, an effective, robust and low-cost water oxidation catalysts(WOCs), and the anodes and photoanodes that perform fast oxygen evolution at low onset potentials, as well as benign conditions are highly desired. In this article we review recent advances in molecular water oxidation catalysts based on the first-row transition metal elements and advances in commonly used semiconductor materials such as α-Fe2O3, WO3, and BiVO4. Finally, we briefly discuss the assembly methods(covalent link, π-π stack, etc.) of molecular catalysts to electrodes and the classic examples of anode in catalytic oxidation of water.
