Effect of Calcination Temperature on the Photocatalytic Activity of Spiel Zn2SnO4

Article Preview

Abstract:

Spinel Zn2SnO4 photocatalysts have been prepared by the solid state reaction. as-prepared samples were characterized by power X-ray diffraction, scanning electron microscope, UV-vis diffuse reflectance spectroscopy and photocatalytic activity measurement. The results show that the reaction temperature have significant effects on the Zn2SnO4 photocatalytic activity . It has also been found that the distribution of the cations in Zn2SnO4 crystal lattice changes with the increase of calcination temperature, causing the local structural fine adjustment that associated with the photocatalytic properties.
