摘要：

In this paper, SnO2 core-shell microspheres with large specific surface area are synthesized through a facile and effective hydrothermal route. The microstructure and photocatalytic properties of the as-synthesized products are investigated. The diameter of microsphere is about 600 nm and the average thickness of the shell is 80 nm. The morphology can be tailored by adjusting the reaction temperature and the dose of Sn precursor. Photocatalytic test reveals that methylene blue can be degraded nearly completely (over 97%) after 30 min UV light irradiation. Demonstration of efficient photocatalytic activity of the SnO2 core-shell microspheres was also made to other organic pollutants such as Congo red aqueous solution and methyl orange aqueous solution under in the same conditions, indicating the versatile potential of such microsphere product in practical applications.
