Boosting selective nitrogen reduction to ammonia on electron-deficient copper nanoparticles
Production of ammonia is currently realized by the Haber–Bosch process, while electrochemical N(2) fixation under ambient conditions is recognized as a promising green substitution in the near future. A lack of efficient electrocatalysts remains the primary hurdle for the initiation of potential ele...

description | Production of ammonia is currently realized by the Haber–Bosch process, while electrochemical N(2) fixation under ambient conditions is recognized as a promising green substitution in the near future. A lack of efficient electrocatalysts remains the primary hurdle for the initiation of potential electrocatalytic synthesis of ammonia. For cheaper metals, such as copper, limited progress has been made to date. In this work, we boost the N(2) reduction reaction catalytic activity of Cu nanoparticles, which originally exhibited negligible N(2) reduction reaction activity, via a local electron depletion effect. The electron-deficient Cu nanoparticles are brought in a Schottky rectifying contact with a polyimide support which retards the hydrogen evolution reaction process in basic electrolytes and facilitates the electrochemical N(2) reduction reaction process under ambient aqueous conditions. This strategy of inducing electron deficiency provides new insight into the rational design of inexpensive N(2) reduction reaction catalysts with high selectivity and activity. |
