چکیده انگلیسی
Synthesis of novel CeO2 nanocubes via simple wet chemical method has described in this manuscript. Since the CeO2 nanoparticles have been admired for their properties and extensive applications in the recent years, the structural properties and morphology of the obtained materials were investigated in detail. The results indicated that formation of CeO2 nanocubes and it act as very dynamic photocatalyst in visible region. When applied to the photocatalytic degradation of Congo red (CR) and methyl orange (MO) dyes, the best results were obtained when using this catalyst which is due to the formation of more reactive oxygen species owing to the presence of Ce4+/Ce3+. The photodegradation efficiency of CeO2 nanocubes was 95% within 100 & 90Â min for CR and MO respectively. Furthermore, the catalyst can be easily recovered and reused until fifth cycles without significant loss of activity.
