Abstract: |
The present invention relates to a method for preparing visible light excitation TiO2 photocatalyst by utilizing industrial metatitanic acid, belonging to the field of nano material preparation technology. In particular, it relates to the preparation of titanium dioxide nano material. Said method includes the following steps: utilizing sulfuric acid method to produce intermediate raw material industrial metatitanic acid of titanium white powder, washing and purifying, solvent displacement and dehydration, adding rare earth element and noble metal element to obtain ultrafine raw material powder, then roasting, making heat treatment and doping so as to obtain the invented product. |
