The samples containing 1–10% tin dioxide supported onto silica gel have been synthesized via precipitation or thermolysis of tin tetrachloride. The prepared samples have been characterized using DTA–TG, XRD, Raman and UV–Vis spectroscopy, TPD of ammonia, and low-temperature nitrogen adsorption–desorption. The supported samples have been tested as photocatalysts in the process of rhodamine B degradation under visible irradiation. It has been established that the deposited phase is uniformly dispersed on the surface. Redshift of band gap is observed for the supported samples. Unlike a bulk SnO 2 , the supported samples exhibit photocatalytic activity under visible irradiation.
