AI Technical Summary
Existing single-atom catalysts have low loading capacity, limited number of active sites, high energy consumption during preparation, and cannot be uniformly distributed, affecting the efficiency and selectivity of electrocatalytic nitrate to ammonia production.
A molybdenum disulfide-based high-loading single-atom iron catalytic electrode was synthesized in situ using a one-step hydrothermal method. The catalyst was uniformly loaded onto a conductive substrate, avoiding the use of binders. Ammonia was prepared by electrocatalytic reduction of nitrate.
Stable dispersion of high-load single-atom iron was achieved, with full exposure of active sites. The Faraday efficiency of electrocatalytic reduction of nitrate to ammonia reached 99%, and the ammonia yield reached 28.59 mg h⁻¹cm⁻². It exhibits good cycle stability and high selectivity.
