Abstract
Developing efficient and easily synthesized oxygen evolution catalysts is crucial for generating clean energy. A low-sulfur (S) doped FeCoNiOx flower-like nanosheet (denoted as S-FeCoNiOx) grown on nickel foam (NF) is presented. The porous structure of the NF, combined with the electronic structure modification from S doping, results in the nanosheets featuring numerous active sites and optimal adsorption strength. Electrochemical tests reveal that the catalyst demonstrates outstanding performance in alkaline electrolytes, characterized by a low overpotential (221 mV @ 10 mA cm−2) and a small Tafel slope of 29.19 mV dec−1, indicating favorable reaction kinetics. A two-electrode system comprising S-FeCoNiOx and Pt/C for water splitting, it exhibits low voltage (1.49 V @ 10 mA cm−2) and superior stability over 40 h. This research emphasizes significant potential applications and offers fresh guidance for creating additional high-efficiency S-doped electrocatalysts for oxygen evolution reactions (OER).
