摘　　要：碱性水电解制氢(AWE)因具有技术成熟、设备成本相对较低的优点,被认为是未来主流的制氢方法。但存在电流密度低、制氢效率低的问题,限制了其在工业上的应用。开发高效析氧(OER)催化材料是解决该问题的主要方法。目前广泛研究的OER催化材料可分为金属氧化物、层状双氢氧化物(LDH)以及其他新结构材料3类。对比了不同OER催化材料的制备方法与性能,发现LDH具有相对良好的OER催化性能。对于工业化应用,OER催化材料还应具备制备简单、成本低、效率高、寿命长及稳定性好的特性。未来碱性水OER催化材料的研发应综合考虑催化性能及工业化要求。Alkaline water electrolysis(AWE)is regarded as the most promising method for hydrogen production due to its high technology maturity and relatively low equipment cost.However,the potential of AWE for industrial applications is limited with its low current density and low hydrogen production efficiency.Developing highly efficient materials for oxygen evolution reaction(OER)is considered as the key to solve this problem.At present,the OER catalytic materials have been widely studied can be divided into three categories:metal oxide,layered double hydroxides(LDH)and other new structure materials.The preparation methods and performances of different OER catalytic materials were compared,and it is found that LDH have relatively good OER performance.For industrial applications,OER catalytic materials should also have the characteristics of simple preparation,low cost,high efficiency,long service life and good stability.The future alkaline water OER catalytic materials should fully combine the catalytic performance and industrial need.
