| Abstract: | Crystalline cubic cerium oxide nano particles have been synthesized from cerium (Ⅲ) nitrate (Ce (NO3)3.6H2O) and sodi-um hydroxide by a hydrothermal method.The effect of three different molar ratios of the NaOH precipitating agent on structur-al,optical,and photo catalytic activity was investigated.The synthesized cerium oxide nano particles were characterized by X-ray diffraction (XRD),a UV-vis spectrometer,scanning electron microscope (SEM),energy-dispersive X-ray spectroscopy (EDAX),Raman spectroscopy and X-ray photo electron spectroscopy (XPS).According to the findings,hydrothermally synthesized ceri-um oxide NPs have a high efficiency for photocatalytic degradation of methylene blue when exposed to UV light.Environment-al water pollution is the major issue of the atmosphere.To get fresh water,humans could search the resources to purify the wa-ter in simple way and degradation is the one of the methods to purify salt water. |
