Surface sulfur-modified NiO nanoparticles with enhanced oxygen evolution reaction kinetics and periodic electrochemical durability evaluation

Developing efficient and durable oxygen evolution reaction (OER) electrocatalysts is essential for sustainable hydrogen production through water electrolysis. Herein, pristine NiO nanoparticles and NiO–S composites containing 10 wt% (NiO@S1) and 20 wt% sulfur (NiO@S2) were prepar...
