| 英文摘要 | CeO2 nanocrystals with different surface structures are synthesized for studying an improvement strategy to the enhanced adsorption removal performance of Congo red. CeO2 nanonetworks possess a cerium-rich surface with more Ce4+. However, CeO2 nanorods have an oxygen-rich surface with more low-temperature reducible oxygen promoted by more defective structures, and the oxygen-rich surface of CeO2 nanoparticles is occupied by more surface-adsorbed oxygen. The effect of CeO2 surface structure is investigated by evaluating the adsorption removal capacity of Congo red. The cerium-rich surface of CeO2 nanonetworks exhibits the distinctly increased adsorption removal performance relative to the oxygen-rich surface of CeO2 nanocrystals. CeO2 nanorods with more easily reducible oxygen surface show higher adsorption removal performance than CeO2 nanoparticles with more surface-adsorbed oxygen due to more favorable textural properties and easy reducibility of more surface oxygen. |
