摘　　要：The escalating energy crisis and worsening environmental challenges underscore the urgent need for sustainable energy alternatives to replace fossil fuels.Molecular hydrogen(H2)has emerged as a promising energy carrier due to its high energy density and environmentally friendly nature,positioning it as a key contender for future energy solutions[1,2].Among various hydrogen production approaches,water splitting driven by electricity has gained prominence for its cost-effectiveness and high energy conversion efficiency[3-6].Platinum(Pt)has long been the benchmark catalyst for hydrogen evolution reaction(HER)due to its optimal hydrogen adsorption free energy(ΔGH∗)[7,8],which facilitates efficient proton reduction and hydrogen desorption.However,the limited availability and high cost of Pt have driven the search for cost-effective,earth-abundant alternatives.Copper(Cu)has attracted interest for its excellent electrical conductivity,low cost,and natural abundance[9].Nevertheless,its inherently weak binding with reaction intermediates leads to poor HER activity,limiting its practical application in water electrolysis.
