摘   要：

Development of efficient and environmentally friendly energy conversion technology has become a top priority with the continuous improvement of global energy demand and environmental awareness. Designing an electrocatalyst with high activity, excellent stability and durability is a major problem in the development of water decomposition. In this study, polymetallic sulfides FeS-Co3S4-Ni3S2/NF (shortened as FeCoNi-S/NF) with nanoflower structure was synthesized by multi-step conventional hydrothermal method. FeCoNi-S/NF demonstrated outstanding electrochemical performance, only overpotential of 174 mV was required to reach a current density of up 10 mA cm-2 for the oxygen evolution reaction (OER) in an alkaline electrolyte. Additionally, FeCoNi-S/NF exhibited remarkable durability and stability during OER and shows high stability of sustainable operation for 40 hours. This research offers a viable solution for the synthesis and application of water decomposition electrocatalysts.
