Electron-deficient Mo sites enhance electrochemical nitrate reduction to ammonia by promoting water dissociation

Nanoporous Mo-doped Co 2 P exhibits outstanding NITRR performance, as the introduction of electron-deficient Mo promotes H 2 O dissociation to *H, enabling efficient NO hydrogenation with nearly 100% NH 3 FE and 40.6% EE at −0.1 V vs. RHE.
