| 英文摘要 | Earth-abundant ni has emerged as an interesting catalytic material toward electrochemical hydrogen evolution reaction (her) in alkaline media, but developing high-performance ni-integrated her catalysts is still a big challenge. herein, we describe the development of self-standing ni-tungsten nitride heterostructure nanowires array on conductive carbon cloth (ni-wn/cc) as a highly efficient 3d hydrogen-evolving cathode in 1.0 m koh with catalytic activity outperforming most reported pt-free her catalysts. this ni-wn/cc electrode exhibits a negligible onset overpotential and a tafel slope of 71 mv dec(-1). it demands overpotentials of only 47, 70, and 155 mv to drive 10, 20, and 100 ma cm(-2), respectively, with its activity being maintained for 10 h. such high hydrogen evolution activities are due to electrocatalytic synergistic effects of ni and wn.
