About This Video-
Researchers used doping with high-valent Mo and W metal centers to improve the performance of multimetallic FeVO(OH)/Ni(OH)2 systems.
The resulting catalyst exhibited a low overpotential of 231 mV for OER and 156 mV for HER at a current density of 20 mA/cm2 in an alkaline medium.
introducing individual W6+ and Mo6+ improved the reaction rate and kinetics for water oxidation, leading to improved water-splitting efficiency.
This study’s results suggest that the catalyst developed by Moi, Sahu, and Qureshi has great potential for efficient water splitting.
The as-synthesized electrocatalyst exhibits a low overpotential of 231 mV for OER and 156 mV for HER at a current density of 20 mA/cm 2.
Doping causes a reduction in the water dissociation energy and optimizes the adsorption energy for the reaction intermediates during the HER and OER processes.
The introduction of individual W6+ and Mo6+ shifts the Ni 2p peak toward higher BEs by 0.4 and 0.7 eV for NiW and NiMo.

Thank you so much..........
