Abstract
In the present world, Nano science in itself is a massive field for conducting research and bringing out interesting insights due to the superior behavioral traits exhibited by nanoparticles. The properties associated with their dependencies on size are an excellent property that makes it different from other types of research. In this research paper, the Nano stuff (NP’s) structures of Al doped CeO2 with varying dopant concentrations, i.e.5%, 10%, 20% are manufactured prosperously by using the uncomplicatedd co-precipitation mechanism where the mixture is calcinated at 600oC for a total of 2 hours. The structure and morphology of the formed metal oxide Nano stuff samples and calcined as synthesized samples has characterized by the diffraction through P-XRD (X-Ray), UV-visible spectroscopy, FTIR spectrum, Transmission electron micrographs signify that the metal oxide Nano stuff sample are crystalline in nature and undergoes a grain size calculated by Debye Scherer’s method is 30 nm and investigated structure is face central cubic structure. The UV visible adsorption spectrum is procured to examine the optical (energy) band gap which is showing the shifting range from 236 eV to 238 eV in the Nano metal oxide samples with variation of dopant concentration respectively. The Fourier transform IR spectrum of given samples disclose that the incorporation of Ce ion with the no. of oxidation state by replacing the position of Al in Al2O3 structure with metal oxide Nano stuff at 484.9 for CeO2and 633.3 for Al2O3.
