Coherent NiS₂@SnS₂nanosheet for accelerating electrocatalytic nitrate reduction to ammonia

The development of an effective and selective catalyst is the key to improving the multi-electron transfer nitrate reduction reaction (NO₃^-RR) to ammonia. Here, we synthesized a coherent NiS₂@SnS₂nanosheet catalyst loaded on carbon cloth via one-step solvothermal method. Experimental data reveals that the integration of NiS₂and SnS₂can enhance the NO₃^-RR performance in terms of high NH₃yield rate of 408.2μg h^-1cm^-2and Faradaic efficiency of 89.61%, as well as satisfying cycling and long-time stability.
