Abstract
A method for manufacturing a photocatalyst, based on titanium dioxide containing carbon or metal, in a pulsation reactor, where a raw material mixture, consisting of nanoparticulate titanium oxyhydrate and an aqueous solution or suspension, containing at least one organic, carbon-containing compound or metal ions, is fed into the pulsating hot-gas stream of the pulsation reactor and the titanium dioxide particles containing carbon or metal are formed. The hot-gas stream has a temperature of ≧450° C. following addition of the material and contains an excess of oxygen. In contrast to the known manufacturing methods, the method according to the invention allows reproducibly good product qualities to be achieved.
