A series of titania-tin oxide binary nanosized mesoporous materials with various composition were successfully obtained by template assisted hydrothermal technique. They were characterized by nitrogen physisorption, XRD, TEM, XPS, UV-Vis, FTIR of adsorbed pyridine and Raman spectroscopes. The reduction properties of the composites were studied by TPR with hydrogen. Two environmental feasible processes, such as total oxidation of ethyl acetate as representative VOCs and decomposition of methanol as hydrogen source, which are also sensitive both to the surface and redox properties of the solids, were used as catalytic tests. On the base of detailed analyses of the data from the complex physicochemical study and comparison with the reference samples, obtained by homogeneous precipitation with urea, a possible mechanism of the formation of TiO2-SnO2binary materials was proposed and discussed in a view of catalyst design control.
