Shape Controlled Synthesis, Structural and Morphological Characterization of CeO2@ZnO@SiO2 Core-Shell Hybrid Nanoparticles
نویسندگان
چکیده
we report the fabrication of pure CeO2, ZnO and SiO2 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) 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 formation of core-shell nanostructure was further confirmed by HRTEM studies. KeywordsCo precipitation; core-shell; cubic-fluorite; HRTEM.

متن کاملFe3O4/SiO2/CeO2 Core-Shell Magnetic Nanoparticles as Photocatalyst
The Fe3O4/CeO2 magnetic photocatalyst was prepared by coating directly onto the surface of magnetic Fe3O4 particles. However a direct contact of CeO2 onto the surface of magnetic Fe3O4 particles presented unfavorable heterojunction, thus the SiO2 barrier layer between magnetic Fe3O4 and CeO2 was prepared as a core-shell stucture to reduce the negative effect by combining three steps of the hydr...
