Abstract: In the quest for sustainable energy solutions, the efficient production of oxygen and hydrogen through water oxidation has emerged as a critical area of research The electrochemical water splitting can fulfill the future global energy demand by producing clean and eco - friendly H2. As the anodic oxygen evolution reaction (OER) of water splitting is kinetically sluggish and accompanied by the input of extra overpotential, a low cost and highly efficient electrocatalyst must be developed for efficient OER activity. Herein, we have explored a room temperature method for the S - doping in NiFeOOH nanosheets for the excellent OER activity. The S - doping in NiFeOOH modulated the electronic structure, increases the number of active sites and improved electrochemical surface area enhancing the OER activity. The S - NiFeOOH showed excellent OER activity and required only 200 mV overpotential to produce 50 mA cm - 2 current density in comparison to un - doped NiFeOOH. Moreover, S - NiFeOOH exhibited 24 h chronoamperometric (CA) stability for the O2 production at high current density.
