摘要
A lattice-oxygen-participated OER electrocatalyst was obtained by in-situ constructing metal (oxy) hydroxides on FeCoNiAl high entropy alloy (HEA). The electrocatalyst exhibits a remarkable activity, requiring a low overpotential of 370 mV to achieve a current intensity of 50 mA cm−2 and performing rapid reaction kinetics with a Tafel slope of 90 mV dec−1.
