Here we report the direct electrodeposition of cerium-doped nickel hydroxide nanosheets on carbon fiber paper and its prominent performance in catalyzing the OER. The composite generates a current density of 100 mA cm^-2 at an overpotential of 320 mV, rivaling the performance of most reported OER catalysts and commercially available RuO₂. X-ray photoelectron spectroscopy analysis shows strong electronic interaction between Ni(OH)₂ and CeO₂, making a great contribution to the OER enhancement.RSC advancesOne-step electrodeposition of cerium-doped nickel hydroxide nanosheets for effective oxygen generation.PMC9064652IRT14R232011DFG52970B130255177221451432006Huang ZFang GCai JZhang CfalseOne-step electrodeposition of cerium-doped nickel hydroxide nanosheets for effective oxygen generation.Efficient electrocatalysts catalyzing oxygen evolution reaction (OER) in alkaline media is highly desirable for large-scale hydrogen production from water splitting.
