A highly effective photocatalyst based on carbon dioxide modified (vlp-TiO 2 ) and very active in sunlight and a process for preparing the same are described. vlp-TiO 2 is prepared by mixing a finely divided titanium compound (BET ≧ 50 m 2 / g) with a carbon-containing material and then heat-treating it at a temperature of 400 ° C. or less. The carbon content is 0.05 to 4% by weight, preferably 0.4 to 0.8% by weight. The product is characterized by only one valid ESR signal at g values of 1.97 to 2.05, in particular g values of about 2.003. The claimed photocatalyst is suitable for the mineralization (oxidation) of impurities and contaminants in liquids and gases.n n n n Photocatalyst, Carbon Modified Titanium Dioxide, Photoactive, Heat Treatment |
