Electrocatalytic nitrate reduction enables the recovery of from water under mild conditions and generates ammonia for nitrogen fertilizer feedstock in an economical green means. In this paper, Co/biomass carbon (Co/BC) composite catalysts were prepared by co-carbonization straw metal–organic framework material ZIF-67 electrocatalytic using hydrothermal annealing methods. The structure disperses catalyst components well provides a wider specific surface area, which is conducive to adsorption provision more reactive active sites. introduction biomass additionally enhances electrical conductivity facilitates electron transport. After electrochemical testing, Co/BC-100 exhibited best performance ammonia, with yield 3588.92 mmol gcat.−1 h−1 faradaic efficiency 97.01% at −0.5 V vs. RHE potential. This study promising approach construction other efficient cobalt-based electrocatalysts.
