Abstract | Fluorite CeO2 nanorods (NRs) with tunable surface defects are successfully prepared via hydrothermal synthesis followed by post-calcination under different atmospheres. Impressively, the CeO2 NRs obtained under mixed Ar and H2 gas at 800°C exhibit superior catalytic activity towards water oxidation under visible light (λ ≥ 420 nm), which is 10 times higher than that of CeO2 NRs treated under air at 800°C. Detailed characterization and theoretical analysis reveal that the rich surface defects including surface oxygen vacancies and Ce3+ ions are the origin of the enhanced water oxidation performance of the CeO2 NRs treated under the reduced atmosphere. |
