Sonochemical preactivation of moist gels of tin dioxide in the presence of additives of chromium(III) oxide, silver nitrate, and zinc acetate with subsequent heat thermal treatment leads to change in the porous and crystal structure of the resulted SnO2 samples obtained via doped with compounds of these metals. The doped samples have a narrower band gap and stronger absorption of visible light. Among the materials studied, Ag/SnO2 displays the highest photocatalytic activity in the oxidation of rhodamine B, safranin T, methyl orange, and phenol upon irradiation with visible light.
