Atomic Dispersed Hetero-Pairs for Enhanced Electrocatalytic CO₂ Reduction.

ABSTRACT: Electrochemical carbon dioxide reduction reaction (CO₂RR) involves a variety of intermediates with highly correlated reaction and ad-desorption energies, hindering optimization of the catalytic activity. For example, increasing the binding of the *COOH to the active site will generally increase the *CO desorption energy. Breaking this relationship may be expected to dramatically improve the intrinsic activity of CO₂RR, but remains an unsolved challenge. Herein, we addressed this conundrum by constructing a unique atomic dispersed hetero-pair consisting of Mo-Fe di-atoms anchored on N-doped carbon carrier. This system shows an unprecedented CO₂RR intrinsic activity with TOF of 3336 h^-1, high selectivity toward CO production, Faradaic efficiency of
