Abstract

Electrocatalytic co-reduction of CO₂ and NO to methylamine represents an appealing route for sustainable methylamine (MMA) synthesis, yet its experimental investigation is still missing. Herein, we develop an atomically dispersed Mo within a Cu matrix (Mo₁Cu) alloy as a high-performance catalyst. Mechanistic investigations reveal the Mo₁-Cu dual site synergy in promoting the co-activation of CO₂/NO to key *HCHO/*NH₂OH intermediates and their C-N coupling for target MMA generation. Notably, Mo₁Cu assembled in an MEA electrolyzer delivers an exceptional faradaic efficiency of 59.4% and an MMA yield rate of 73.64 mmol h^-1 g^-1 along with robust stability for over 120 h of electrolysis.
