Control of the crystallinity in TiO2 microspheres through silica impregnation†
Abstract
The crystal grain size as well as the crystallinity in nanoscale TiO2 have been determined to be of importance to the photocatalytic activity, however it is difficult to control while maintaining a high surface area. Here we demonstrate the synthesis of anatase titania microspheres with controllable grain sizes, which are obtained by impregnating the porous networks of amorphous titania microspheres with silicate oligomers through the addition and
