“…The NO2 generated by the reaction quickly reacts on the electrode surface to produce adsorbed nitric oxide (NO), which is an important intermediate for the generation of N2 and NH4 [32] . Subsequently, the adsorbed NO is desorbed from the electrode surface into the solution, and the NO in the solution can form weakly adsorbed nitrous oxide (N2O) with the adsorbed NO, which is further reduced to nitrogen (N2) [36] . Formula (3-9) [37] NO3 -(aq)→NO3 -(ads) (3) NO3 -(ads)+2H + +2e -→NO2 -(ads)+H2O (4) NO2 -(ads)+2H + +e -→NO(ads)+H2O…”

Nitrate is a common pollutant in surface water and groundwater. Electrocatalytic nitrate reduction method is an electrochemical reduction reaction of nitrate at the cathode by impressed current, and the reduced ammonia generated by the reaction is an important chemical raw material. The main step of this process is the selection of cathode electrocatalytic materials. In this paper, the mechanism of electrocatalytic nitrate reduction to ammonia production is briefly explained, then the research situation of transition metals Cu, Fe and Ni as electrode materials for electrocatalytic nitrate reduction to ammonia production at home and abroad is reviewed, and finally the future direction of electrocatalytic nitrate reduction to ammonia production is summarized.
