Abstract EN
Ti-supported RuO2-Co3O4-CeO2 (Ru0.3Co0.7−xCex oxide, 0≤x≤0.7) electrodes were prepared by sol-gel process.
The phase structure, surface morphology, and microstructure of the oxide layer were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM).
Electrocatalytic activity and oxygen evolution reaction (OER) kinetics on these electrodes in 1.0 mol⋅dm−3 KOH solution were studied by recording open-circuit potential, cyclic voltammetry, and polarisation curves.
The results showed that the appropriate content of CeO2 could reduce the grain size and increase active surface area.
The electrocatalytic activity shows a strong dependence on the CeO2 content in the film.
Catalytic performance of mixed oxide electrodes with 40 mol % CeO2 was the best, with the greatest voltammetric charge, 86.23 mC⋅cm−2, and the smallest apparent activation energy for OER at 0.60 V was 22.76 kJ⋅mol−1.
