Abstract

 
There is a continuous demand and burning of limited fossil fuel prompted the urgent need to develop renewable, abundant, and clean energy source. There- fore, for solving the energy crisis, the production of green hydrogen by elec- trochemical water splitting plays a vital role in achieving this goal. But, this electrochemical energy production process is kinetically sluggish due to multi- electron transfer reactions Therefore, the development of an efficient inexpen- sive catalyst towards OER have been required to accelerate the rate of oxy- gen evolution. We effectively designed and synthesized sheet-like morphology of lanthanum doped cobalt selenate through the one-pot hydrothermal route. The synthesized material is confirmed by different techniques. Herein prepared sheet-like La doped CoSe2O5 material is employed as an efficient electrocata- lyst towards OER in alkaline medium. This electrocatalyst show the low Over- potential and the low the Tafel slop value. Also successfully doped with the rare earth metal it show the large exchange current density and the active sites.
