Two step synthesis of a mesoporous titania-silica composite from titanium oxychloride and sodium silicate

► A two step method to produce titania-silica composite was introduced. ► Transparent TiO2 sol obtained from TiOCl2 was reacted with sodium silicate. ► No surfactants were used to form mesoporous titania-silica composite. ► A product with desired properties (porosity and surface area) was obtained.
