Coherent NiS2@SnS2 nanosheet for accelerating electrocatalytic nitrate reduction to ammonia

Abstract The development of an effective and selective catalyst is the key to improving the multi-electron transfer nitrate reduction reaction (NO 3 – RR) to ammonia. Here, we synthesized a coherent NiS 2 @SnS 2 nanosheet catalyst loaded on carbon cloth via one-step solvothermal method. Experimental data reveals that the integration of NiS 2 and SnS 2 can enhance the NO 3 – RR performance in terms of high NH 3 yield rate of 408.2 μ g h −1 cm −2 and Faradaic efficiency of 89.61%, as well as satisfying cycling and long-time stability.
