Abstract
Provided is a method of fabricating silica-titania nanoporous composite powder by controlling a pore size. In more particular, a method of fabricating silica-titania nanoporous composite powder, using a spraying and heating reactor including an ultrasonic droplet generator and a cylindrical electric furnace, comprises the steps of: generating droplets of a mixture suspension from a colloidal suspension prepared by mixing silica (SiO) and titania (TiO) nanopowders and organic template (PSL: polystyrene latex) powder, by the ultrasonic droplet generator of the spray-heating reactor; generating a silica-titania-organic template nanoporous composite powder having pores within the range of 20˜100 nm in size through preparing silica-titania-organic template (SiO—TiO-PLS) composite particles and removing the organic template while passing the mixture suspension in the cylindrical electric furnace by a carrier gas; and collecting the generated nanoporous material by a particle collector.
