电解水制氢是生产氢气的重要方法，对未来能源的可持续发展至关重要。析氧反应的高势垒和反应过程中的多电子转移导致其动力学反应速率缓慢，在阳极上负载析氧催化剂，可以降低电解过程耗能，提高制氢效率。近年来为降低工业制氢成本，碱性大电流电解水析氧催化剂受到广泛的关注。本文首先介绍了电解水制氢的原理和析氧反应在碱性电解质下的反应机理。然后，总结了近年来报道的碱性大电流电解水析氧催化剂的研究进展，主要包括贵金属基析氧催化剂和非贵金属基析氧催化剂。最后对未来大电流析氧催化剂的发展方向做了展望。
Hydrogen production by electrolysis
of water is an important method to produce hydrogen, which is crucial to the sustainable development of
energy in the future. The high potential barrier of oxygen evolution
reaction and the multi-electron transfer in the reaction process lead to the
slow kinetic reaction rate. Loading oxygen
evolution catalyst on the anode can reduce the energy consumption in the
electrolysis process and improve the hydrogen production efficiency. In recent
years, in order to reduce the cost of industrial hydrogen production, alkaline
high-current electrolyzed water oxygen evolution catalyst has been widely
concerned. Firstly, this paper introduces the principle of hydrogen production
by electrolysis of water and the reaction mechanism of oxygen evolution in alkali electrolyte. Then, the
research progress of as-reported alkaline high-current electrolysis of water oxygen evolution catalysts
in recent years is summarized, including noble metal-based oxygen
evolution catalysts and non-noble metal-based oxygen evolution catalysts.
Finally, the development direction of high current oxygen evolution catalyst in
the future is prospected.
