Key Points

The research aims to develop cerium doped nickel sulfide electrodes with enhanced electrocatalytic effectiveness for hydrogen and oxygen evolution.
Prepared cerium doped nickel sulfide materials via hydrothermal synthesis.
Conducted electrocatalytic experiments to evaluate performance in hydrogen and oxygen evolution reactions.
Compared the electrocatalytic overpotential of different electrode materials.
Ce-Ni 9 S 8 -3 exhibited the lowest overpotential during the oxygen evolution reaction.
At specified current densities, Ce-Ni 9 S 8 -3 showed overpotentials of 264.6 mV, 310.6 mV, and 348.6 mV.
Found that the slope of Ce-Ni 9 S 8 -3 was 19.39 mV/dec, indicating efficient catalytic behavior.

Implication

Electrocatalytic experiments show superior performance in bifunctional electrocatalysis, suggesting efficient design approaches.
