Abstract
Abstract In this paper, a novel strategy was used to grow CeO2/Ce(OH)CO3 composite in situ by the incomplete conversion of CeO2 to Ce(OH)CO3 using ethylene glycol (EG) as CO32− source and solvent. And the content of Ce(OH)CO3 in CeO2/Ce(OH)CO3 composite can be controlled by changing the solvent composition. The CeO2/Ce(OH)CO3 composite prepared at 200°C for 24 h with a H2O/EG volume ratio of 10:20 exhibited greatly enhanced visible-light activity for methylene blue (MB) degradation compared to the bare CeO2. This work would provide a novel method to fabricate basic rare earth carbonates and their composites.
