Abstract
There is provided a highly porous amorphous titania or titania/silica material. The material may be prepared by gelling a reaction mixture comprising hydrolyzable titanium and optionally, hydrolyzable silicon compounds, such as titanium diisopropoxide (2,4-pentanedionate) and tetraethylorthosilicate, a nonaqueous solvent, such as ethanol, and water, followed by drying the gel. The titania or titania/silica material may be used as a catalyst, a catalyst support or a sorbent.
