Hydrogen Evolution Reaction: A New Platinum‐Like Efficient Electrocatalyst for Hydrogen Evolution Reaction at All pH: Single‐Crystal Metallic Interweaved V 8 C 7 Networks (Adv. Energy Mater. 23/2018)

Abstract

In article number 1800575, Xiao Gu, Yu Wang, and co-workers report a novel platinum-like, double-deck carbon coated V8C7 network with the highly active (110) facet exposed, as an efficient hydrogen evolution reaction (HER) electrocatalyst in the whole range of pH. Electrochemical tests and theoretical simulation indicate that the metallic character of V8C7, high-activity of exposed facet, and low barrier energy for water dissociation contribute to the catalytic activity.
