【 摘 要 】

tsA promising solar-powered environmentally friendly process for the synthesis and application of catalysts for hydrogen evolution reaction has been proposed.A delicate NiCo(OH)x-CoyW catalyst with a bush-like heterostructure was realized via gas-template-assisted electrodeposition, followed by electrochemical etching process.The excellent catalytic effect of NiCo(OH)x-CoyW for the hydrogen evolution reaction was systematically investigated through various physical and electrochemical analyses.
