abstract In this study, nanocrystalline ZnO-SnO2 mixed metal oxide powder was prepared by co-precipitation using Zn(CH3COO)(2)a (TM) 2H(2)O and SnCl(4)a (TM) 5H(2)O as precursor materials. The powder was characterized by X-ray diffraction, scanning electron microscopy, and Fourier transform infrared spectroscopy. Williamson-Hall method was used to evaluate the micro structural parameters of ZnO-SnO2 such as crystallite sizes and lattice strain. The photoluminescence property of the sample was studied at different temperatures (10-300 K). Results showed that the emission intensity decreases with temperature increasing. The photocatalytic activity at the gas-solid interface was assessed by monitoring the degradation of nitrogen oxides, a major atmospheric pollutant. The results show that the nanocrystalline ZnO-SnO2 mixed metal oxide powder exhibits higher and more stable photocatalytic activity against photocorrosion than ZnO alone. [GRAPHICS] .
