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.
