质子交换膜水电解是解决能源和环境问题的关键技术。然而，电催化剂在酸性析氧反应（OER）环境中的耐久性差阻碍了PEMWE的大规模应用。在此，一个强大的RuMn电化学催化剂具有显着的耐久性内20 000循环伏安循环报道。此外，RuMn在10 mA cm（-2）电流密度下在0.5 M H2SO 4溶液中稳定720 h，
Proton exchange membrane water electrolysis (PEMWE) is a key technology to solve the serious energy and environmental problems. However, the poor durability of electrocatalysts in acidic oxygen evolution reaction (OER) environment hinders the large-scale application of PEMWE. Herein, a robust RuMn electrochemical catalyst with a remarkable durability within 20 000 cyclic voltammetry cycles is reported. Furthermore, RuMn is stable for 720 h at 10 mA cm(-2) current density in 0.5 M H2SO4 solution with
