Hydrogen Evolution Reaction: Synergistically Tuning Water and Hydrogen Binding Abilities Over Co4N by Cr Doping for Exceptional Alkaline Hydrogen Evolution Electrocatalysis (Adv. Energy Mater. 41/2019)

In article number 1902449, Shengli Chen, Wei Luo, and co-workers report a general approach for boosting the alkaline hydrogen evolution reaction performance of Co4N though synergistically tuning the water and hydrogen binding abilities by Cr doping, resulting in a low overpotential of 21 mV to achieve the current density of 10 mA cm−2 and long-term stability in alkaline media.
