Cost‐effective and Efficient Catalyst of Bimetallic Nickel Iron Selenide toward Oxygen Evolution Reaction

Abstract

Abstract The incorporation of additional metal to form homo/heterojunction nanomaterials may enhance electrical conductivity and electrocatalytic performance. In this work, a novel Ni−Fe‐Se compound made through a facile solvothermal method with the presence of D‐(+)‐glucose (labeled as Ni 0.5 Fe 0.5 Se 2 /C) exhibited outstanding catalytic activity toward water oxidation. During oxygen evolution reaction (OER) process in alkaline condition, Ni 0.5 Fe 0.5 Se 2 /C catalyst shows an overpotential of 254 mV at 10 mA cm −2 , 77 mV lower than that of the commercial RuO 2 , and an excellent stability.
