Title

SANS investigations on spray hydrolyzed mesoporous titania grains and its composites

Abstract

Titania is an important material because of its significant role in environmental purification, given its photocatalytic properties. Spray hydrolysis is facile technique to synthesize such materials on industrial scale. Recently various morphologies of the spray hydrolyzed titania grains have been obtained by the control of physicochemical conditions. Titania composites are synthesized using this technique to achieve higher efficiency for solar spectrum. Titania microspheres will be doped with various elements such as N or C for improved photocatalytic application by tuning its band gap. The mesoscopic structure plays a very important role to get better photocatalytic activity. SANS/USANS is a unique tool to probe internal/overall structure of such grains. We propose to perform SANS (0.01 - 4 nm-1) and USANS experiments (0.0001 nm-1 -0.05 nm-1) covering a wide q range (~ 0.0001 to 4 nm-1)on spray-hydrolyzed porous titania grains and its composite prepared under various conditions. The closed and open porosity in these grains will be differentiated by performing contrast matching experiments.In addition,structure of the composites will be resolved by contrast match experiments.
