Defect-rich walnut-like copper-doped Ni(PO₃)₂ catalyst towards ammonia borane electrooxidation reaction with high performance

Abstract

Cu doped Ni(PO 3 ) 2 was applied as an electrocatalyst to ABOR for the first time, which showed an excellent electrocatalytic activity due to the optimized electronic structure and the increased active sites induced by the Cu doping.
