摘要：

Due to the rapid development of Anion-Exchange Membrane Fuel Cell (AEMFC), the development of non-noble metal electrocatalysts for hydrogen oxidation (HOR) in alkaline media has become urgent. Herein, the low-cost MoeCo(2)P/CoP catalyst was synthesized, which can be used as a HOR electrocatalyst in alkaline medium. The improved performance is due to the surface modification of Mo species exposed to air oxidized, and the addition of Mo oxidized species accelerated the alkaline hydrogen electrode kinetics process. The development of active, inexpensive and stable HOR catalysts is of great significance for the commercialization of AEMFC. (C) 2021 Hydrogen Energy Publications LLC. Published by Elsevier Ltd.
