Enhanced electrocatalytic nitrogen reduction on a three-dimensional Cu3P/SnP@CF catalyst through a multi-site synergistic effect between the heterointerface and phosphorus vacancies

An interesting multi-site tandem synergistic effect was observed, in which phosphorus vacancies increase the N 2 adsorption rate, and then, the Cu 3 P/SnP@CF heterojunction lowers the energy barrier of rate-limiting hydrogenation reactions of the NRR.
