Abstract

We report VB₂as an efficient electrocatalyst for NO-to-NH₃electroreduction (NORR), showing the highest NH₃-Faradaic efficiency of 89.6% with the corresponding NH₃yield rate of 198.3 μmol h^-1cm^-2at -0.5 V vs RHE. Theoretical calculations demonstrate that B sites of VB₂act as the key active centers which can facilitate the NORR protonation energetics and inhibit the competitive hydrogen evolution, boosting both NORR activity and selectivity.
