- W3204982512 abstract "AbstractCerium and dysprosium co-doped ZnO nanoparticles were synthesized through a simple co-precipitation approach at low temperature. X-ray diffraction was used for the structure and purity analysis of the samples prepared. A hexagonal wurtzite structure was observed with no secondary peaks. The average crystallite size was about 35 nm. Morphology was studied using scanning electron microscopy. A change in morphology from elongated nanorods to nanoflowers was observed as the concentration of dopants increased. The photocatalytic activities of the nanoparticles were examined by photodegradation of rhodamine B (RhB) under UV irradiation. The experiment revealed a total degradation of the organic molecules indicated by the elimination of the dye color. The result showed that ZnO photocatalyst, co-doped with cerium and dysprosium (Zn0.90Ce0.05Dy0.05), exhibited much improved photocatalytic performance (98% degradation) in comparison with undoped ZnO. The enhanced photocatalytic performance of co-doped samples could be credited to increase in surface oxygen vacancies, improved absorption capacity, and delayed recombination of photogenerated electrons and holes owing to the creation of trap states in the bandgap of ZnO.KeywordsZnOCeDy co-dopingPhotocatalysisRhodamine B dyeRare earths" @default.
