Abstract

Superfine cerium-zinc oxides Ce1−x Zn x O2−x with x = 0, 0.1, 0.3, 0.5, and 1.0 were obtained by grinding Ce(SO4)2·2O, ZnSO4·7H2O and NH4HCO3 under the condition of surfactant PEG-400 being present at room temperature, washing the mixture with water to remove soluble inorganic salts, drying at 80°C, and calcining. The precursor and its calcined samples were characterized using thermogravimetry and differential thermal analyses (TG/DTA), UV-vis absorption spectroscopy, X-ray powder diffraction (XRD), and scanning electron microscopy (SEM). The results showed that superfine Ce1−x Zn x O2−x behaved as an excellent UV-shielding material. The ZnO-doped CeO2 can facilitate the formation of crystalline state CeO2. The catalytic ability of products used in air oxidation of castor oil was investigated. The results showed that the catalytic abilities of products decreased with increasing zinc amount.
