CeO2-SnO2 nanocomposite, a sensing material, was successfully synthesized by a hydrothermal method. The structural, optical and morphological properties of as-prepared CeO2-SnO2 nanocomposites were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), UV-Vis diffuse reflectance spectroscopy and field emission scanning electron microscopy (FESEM). |
