摘要：

In this study we report the fabrication of pure CeO2, ZnO deposited CeO2 hybrid core-shell nanoparticles by simple and cost effective co precipitation method. The as synthesized samples were characterized by various experimental techniques such as XRD (X-ray diffraction), FTIR (Fourier Transform Infrared Spectroscopy), UV-Vis absorbance and HRTEM (High Field Transmission Tunneling Microscopy) measurements. XRD results confirm the Cubic fluorite structure for CeO2 and hexagonal structure for ZnO nanoparticles. Functional groups present in the core-shell nanoparticles was investigated by FTIR. The optical absorbance was measured by UV-vis spectrometer. The formation of core-shell nanostructure was further confirmed by HRTEM studies.
