A corrosion-etching strategy for fabricating RuO2 coupled with defective NiFeZn(OH)x for a highly efficient hydrogen evolution reaction

A facile corrosion-etching strategy is applied to synthesize RuO 2 coupled with defective NiFeZn(OH) x , which efficiently improves the poor intrinsic conductivity of NiFe hydroxide and reduces the kinetic energy barrier of Volmer step for HER process.
