Synthesis and characterization of surfactant assisted CeO2/ZrO2 nanocomposite
نویسنده
چکیده
This paper reports the synthesis of CeO2/ZrO2 nanocomposite by wet chemical method using cationic surfactant (CTAB). The properties of the obtained nanocomposites were analysed by X-ray diffraction (XRD), Fourier transform infrared (FTIR), scanning electron microscoy (SEM), transmission electron microscopy (TEM), UV-Diffuse Reflectance Spectroscopy (UV-DRS) and photoluminescence (PL) spectroscopy. XRD results confirm the formation of the crystalline nature and the mixed phase of CeO2/ZrO2 nanocomposites. FTIR and EDX results confirm the formation of Ce-O and Zr-O bond. The TEM studies revealed the spherical morphology of the CTAB assisted CeO2/ZrO2 nanocomposites in the size range of 26.8 nm. The UV-DRS studies revealed the bandgap value of CeO2/ZrO2 nanocomposites. The photoluminescence properties of CeO2/ZrO2 nanocomposites were observed in the strong UV region and several visible region peaks are likely to have originated from the oxygen vacancies.

Chemical Precipitation of BaCeO3 – CeO2 Based Nano-ceramic Composite Oxide Materials and Their Physical Characterization
In order to reduce the operating temperature of solid oxide fuel cells (SOFCs), novel electrolyte materials based on CeO2 and BaCeO3 are being developed in the scientific realm. In this context, we propose a new methodology for preparing the nano-ceramic composite materials such as BaCe0.9Gd0.9O3-δ – Ce0.9Gd0.9O2-δ (BCGO–CGO) and BaCe0.8Sm0.2O3-δ – Ce0.8Sm0.2O2-δ (BCSO – CSO) as possible elec...
