Self-Assembly of Flower-Like CeO₂ Microspheres via a Template-Free Synthetic Approach and its Use as Support in Enhanced CO and Benzene Oxidation Activity

Abstract:

This work reported that porous flower-like CeO2 microspheres have been successfully synthesized via a controlled template-free precipitation method and were used as catalyst support for the oxidation of CO and benzene. The scanning electron microscopy results showed that ceric concentration has great influence on the morphology of CeO2 micro and nanostructures. This flower-like CeO2 microstructure exhibited a superior low-temperature catalytic activity used as catalyst support compared with conventional CeO2 nanoparticles. The enhanced catalytic activity of flower-like CeO2 microspheres could be attributed to its porous structure and the abundant oxygen vacancies on the surface.
