TiO A method for preparing heat treated zinc doped titanium dioxide photocatalyst

摘要

The invention 1), pure TiO ₂ And distilled water, followed by stirring to prepare zinc-doped TiO ₂ ; 2) step 1) a zinc-doped TiO ₂ to a heat treatment comprising heating to a temperature of 600 ℃ to 1000 ℃ and zinc-doped TiO ₂ produced in And a method for producing the photocatalyst. The heat-treated and zinc-doped TiO ₂ produced by the process of the present invention The photocatalyst is TiO ₂ through the body of the zinc doping and thermal processing - chemical fine adjustment is possible, and this general nature of the pure TiO ₂ through It is possible to provide a TiO ₂ photocatalyst which exhibits a higher photocatalytic decomposition effect as compared with a photocatalyst and reacts at a high efficiency in a visible light region.
