Patent ID: 8070981

Claim:
A method of fabricating silica-titania nanoporous composite powder, comprising: preparing a silica-titania-organic template mixture suspension comprising 1-10 wt % of a silica-titania-organic template nanopowder mixture by mixing a silica-titania nanopowder mixture consisting of 50-99 wt % silica nanopowder and 1-50 wt % titania nanopowder with an organic template nanopowder in a suspension; spraying the silica-titania-organic template mixture suspension to generate fine droplets by a droplet generator; drying the sprayed droplets of the silica-titania-organic template mixture suspension in a low temperature region of an electric furnace at 100-400Â° C. to provide a dried silica-titania-organic template mixture powder; and heating the dried silica-titania-organic template mixture powder in a high temperature region of the electric furnace at 600-800Â° C. to remove the organic template nanopowder.
