摘　　要：利用电解水制氢来储存太阳能是未来能源发展的一大趋势。水的阳极氧化是这一过程中最重要也是最复杂的一步。因此,设计稳定而高效的水氧化催化剂是电解水制氢的关键。目前,研究比较成熟的是基于贵金属钌的水氧化催化剂,但由于其价格昂贵、储量较少无法大规模利用。铁作为钌的同族元素用于水氧化催化近年来受到了越来越多的关注。本文从铁基阳极水氧化催化剂研究现状、制备方法、催化体系及机理3个方面对电解水铁基阳极催化剂进行了综述。分析其当前存在的问题,为水氧化催化剂的进一步研究设计提供参考。Converting solar energy to hydrogen by water splitting is a major trend of the future energy development. Water oxidation is in the most important and complex step in the conversion. So it is critical to design a stable and efficient catalyst for the water oxidation. The development of Ruthenium-based water oxidation catalyst tends to maturity. However, its utilization is limited by the high price and low reserves. In recent years, iron as the same group of ruthenium for catalytic oxidation of water has received increasing attention. Here we summarize the progress of classification of iron-based water oxidation catalyst, the preparation method, and the catalytic system and mechanism. By analyzing current problems, we try to provide some reference for further design of water oxidation catalysts.
