Abstract: A method for fabricating SnO2 nanoparticles is provided to maximize the specific surface area of the SnO2 nanoparticles, which results from the phase separation of titania and tinoxide. A method for fabricating SnO2 nanoparticles comprises: a first step of synthesizing Sn isopropoxide and Ti isopropoxide in a sol-gel process so as to obtain nanoparticles including SnO2 and TiO2; a second step of heating the nanoparticles within a spinodal line and separating into titania and tinoxide; and a third step of eliminating the titania using an etching solution, which can selectively etch titania, so that the tinoxide nanoparticles remain.

Abstract: A titania/selenide nanostructures forming method is provided to improve optical and optical catalyst properties by adhering cadmium selenide nanopowders to a titania nanowire and increasing a surface area. A titania/selenide nanostructures forming method comprises steps of: forming a first substrate in which a titania nanowire layer is formed on a substrate; preparing a cadmium selenide mixture solution having cadmium selenide nanopowders; coating the cadmium selenide mixture on a titania nanowire layer of a first substrate and forming a second substrate; and heat-treating the second substrate. The substrate is a sapphire substrate or a titanium substrate.
