Electrochemical nitrate reduction to ammonia is a promising alternative strategy the traditional Haber-Bosch process but suffers from low Faradaic efficiency and limited yield due sluggish multi-electron/proton-involved steps. Herein, we report typical hollow cobalt phosphide nanosphere electrocatalyst assembled on self-supported carbon nanosheet array synthesized with confinement that exhibits an extremely high rate of 8.47 mmol h
