Atomic Precision CoCu Heterodimers with Pseudo-D_3h Symmetry Enable Tandem Nitrate Reduction.

ABSTRACT: The electrochemical reduction of nitrate (eNO₃RR) to ammonia (NH₃) is an efficient method for mitigating nitrate (NO₃ ^-) pollutant while offering sustainable NH₃ generation under ambient environments. However, optimizing NO₃ ^- adsorption on catalytic surfaces and promoting adsorbed hydrogen formation remain challenging. Herein, we introduce pulsed laser irradiation in liquid for the first time to design a metal-metal-ligand-coordinated CoCu heterodimer catalyst with a pseudo-D_3h symmetry anchored on nitrogen-doped graphene oxide (CoCu-HeD/NGO), enabling a tandem catalytic effect for the eNO₃RR. The catalyst reaches a remarkable Faradaic efficiency of 91% at -0.4 V vs. RHE and a high NH_3<
