The electrochemical nitrogen reduction reaction (eNRR) has emerged as a promising strategy for green ammonia synthesis. However, it suffers unsatisfactory performance owing to the low aqueous solubility of N2 in solution, high dissociation energy N≡N, and unavoidable competing hydrogen evolution (HER). Herein, MIL-53(Fe)@TiO2 catalyst is designed synthesized highly efficient eNRR. Relative simple MIL-53(Fe), achieves 2-fold enhancement Faradaic efficiency (FE) with an improved yield rate by 76.5% at −0.1 V versus reversible electrode (RHE). After four cycles electrocatalysis, can maintain good catalytic activity, while MIL-53(Fe) exhibits significant decrease NH3 FE 79.8 82.3%, respectively. Benefiting from synergetic effect between TiO2 composites, Fe3+ ions be greatly stabilized during eNRR process, which hinders deactivation caused ions. Further, charge transfer ability interface composites improved, thus, activity significantly boosted. These findings provide insight into preparation composite electrocatalysts.
