Abstract

A Ru@WO_3−x–W/TM catalyst with WO_3−x(surface)–W(bulk) structure was carefully designed and prepared. Compared with W or WO₃ support, the presence of WO_3−x–W modifies the electronic structure, optimizes H adsorption/desorption and promotes hydrogen spillover with Ru. The Ru@WO_3−x–W/TM catalyst can generate an industrial HER current density of 1204 mA cm⁻² in an acidic system.
