Herein we report the controllable surface modification of nickel\u2013nitrogen (Ni\u2212N) bridge sites on metallic Ni particles via a simplified vapor\u2010assisted treatment approach. X\u2010ray absorption spectroscopy (XAS) and Operando Raman spectroscopy verifies the interaction between Ni and surface\u2010anchored N, which leads to distorted Ni lattice structure with improved wettability. The Ni\u2212N bridge sites with appropriate N coverage level plays a critical role in the enhanced hydrogen evolution reaction (HER) and the optimized electrode (Ni\u2212N<jats:sub>0.19<\/jats:sub>) has demonstrated superior HER performances with low overpotential merely of 42\u2005mV for achieving a current density of 10\u2005mA\u2009cm<jats:sup>\u22122<\/jats:sup>, as well as favorable reaction kinetics and excellent durability in alkaline electrolyte.

Furthermore, this generic synthetic approach can also be applied to prepare S\u2010modified Ni HER catalyst by generating hydrogen sulfide vapor.<\/jats:p>","DOI":"10.1002\/anie.201808629","type":"journal-article","created":{"date-parts":[[2018,10,24]],"date-time":"2018-10-24T09:17:43Z","timestamp":1540372663000},"page":"461-466","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":130,"title":["Processable
