It is highly promising to design and develop efficient and economical electrocatalysts for oxygen evolution reaction (OER) in alkaline solution. In this work, we prepare FeCoNi sulfide composites (including FeS, CoS, and NiS) derived from sulfurization of precursor oxides on carbon cloth (CC), which are used to become an OER catalyst. Such catalyst shows excellent OER performance, low overpotential, small Tafel slope, and high electrochemical stability, and it is a promising electrocatalyst for OER in alkaline media.
设计和开发用于碱性溶液中析氧反应（OER）的高效且经济的电催化剂具有很大的前景。在这项工作中，我们制备了由碳布（CC）上的前驱体氧化物硫化得到的FeCoNi硫化物复合材料（包括FeS、CoS和NiS），并将其用作OER催化剂。这种催化剂表现出优异的OER性能、低过电位、小塔菲尔斜率和高电化学稳定性，是一种在碱性介质中用于OER的有前景的电催化剂。
