Coadsorption of NRR and HER intermediates determines the {performance|overall performance|efficiency|functionality} of Ru-N4 towards electrocatalytic N2 reduction

Electrochemical N2 reduction (NRR) to ammonia is seriously {limited|restricted} by the competing hydrogen evolution reaction (HER) but atomic-scale {factors|elements|aspects|variables|components|things} controlling HER/NRR {competition|competitors} are unknown. Herein we unveil the mechanism, thermodynamics,…
