摘　　要：质子交换膜(PEM)电解水作为一项高效制氢技术在可再生能源储能方面有巨大的潜能,降低PEM电解水的成本是研究的重点。对阳极氧析出反应(OER)催化剂进行分类:非贵金属掺杂型催化剂,单原子催化剂以及非贵金属催化剂。非贵金属掺杂催化剂在掺杂成分的活性与稳定性兼顾方面仍然有一定的挑战。单原子催化剂在大幅降低贵金属含量(质量分数小于5%)、提升活性(过电势220~270 mV@10 mA/cm^(2))方面具有明显优势,但其发展往往需要借助特异性结构的载体材料,如氧缺陷型二氧化钛、金属有机框架材料(MOFs)、迈克烯等。非贵金属催化剂的研究目前较少,相比贵金属催化剂,其活性相差甚远。The proton exchange membrane(PEM)water electrolysis is an effective pathway to produce hydrogen and obtains huge potential for renewable energy storage.Cutting down the loading of noble metal is urgent to achieve a low-cost technology.The anode(oxygen evolution reaction,OER)catalysts could be summarized and classified as:traditional catalyst doped by non-noble metal,single-atomic catalyst and non-noble catalyst.For the traditional doping catalyst,it is difficult to keep balance between activity and stability.The single-atomic catalyst has advantages in reducing noble metal(less than 5%mass fraction)and elevating electrochemical activity(overpotential 220-270 mV@10 mA/cm^(2)).However,the single-atomic catalyst is generally supported and stabilized by specific coordination environment of carriers,such as oxygen-deficient TiO2,MOFs and MXene.There are few researches on non-noble metal catalyst,and its activity is far from that of noble metal catalysts.
