(a) Comparison of conventional thermal, catalytic, and electrocatalytic pathways for AN hydrogenation. The thermal route often suffers from low selectivity and undesirable byproducts, while the electrochemical approach enables greener and highly selective EA synthesis. (b) Electronic structure modulation of metal sites induced by Eu doping, demonstrating its potential to regulate the adsorption configuration of key reaction intermediates. (c) Proposed mechanism of Eu-mediated transition of the AN intermediate from flat π-adsorption to vertical N-end vertical adsorption, facilitating efficient protonation and suppressing competing hydrogen evolution.
