Synthesis by flame hydrolytic doping results in SiO2/TiO2 materials with a variety of surface morphologies that have potential advantage as catalyst supports.  Under sintering conditions (thermal and hydrothermal), a subset of these materials demonstrates that doping allows the base titania to be stable against sintering by resisting crystallite growth.
