SYNTHESIS AND STRUCTURAL CHARACTERIZATION OF UNDOPED CEO2 AND PD DOPED CEO2 FOR PHOTO CATALYTIC STUDIES UNDER SUNLIGHT AND UV-LIGHT IRRADIATION.

Abstract

The main objective of the analysis is concentrated on the preparation and fabrication of doped and undoped CeO₂ nanoparticles by solution combustion technique to taken glycine as fuel. The correct size and morphology of the doped metal compounds were studied Scanning microscope (SEM). The composition of ceria (CeO₂) and palladium substituted Ceria (Ce_0.98Pd_0.02O₂) was confirmed from the powder X-ray Diffractometer (PXRD). The functional groups were analyzed by Fourier transfer infrared spectroscopic analysis, XRD, RR, UV–Vis, and XPS. Photocatalytic properties of CeO₂ and palladium doped CeO₂ (Ce_0.98Pd_0.02O₂) nanoparticles (NPs) were studied using the radiation conjugation of red (CR) under UV light and sunlight exposure. Based on the XRD analysis, CeO₂ and Pd doped CeO₂ NPs were formed as crystal structures. CeO₂ and Pd doped CeO₂ showed excellent Photocatalytic activity by degrading more than 92% of the CR color in the intervals of 120 min under UV light and sunlight.
