Anatase-type TiO 2 nanopowders less than 10nm in average diameter were synthesized by a chemical vapor synthesis method. The TiO 2 nanopowders showed very poor photocatalytic properties, in spite of their large surface area. With subsequent heat treatment of the TiO 2 powders, their photocatalytic properties determined by measuring the degradation of 2-propanol were improved...
Bimetal incorporated TiO 2 photocatalysts (FeZn–TiO 2 ) prepared by a flame method showed high photocatalytic activity for the degradation of 2-propanol dissolved in water as compared with mono-metal incorporated or unincorporated TiO 2 . By using this flame method, parameters such as uniform particle size, crystallinity as well as the anatase and rutile phase ratio (anatase/rutile)...
