| titleOfInvention | PHOTOCATALIZER FOR WATER DISTILLATION AND PROCEDURE FOR OBTAINING |
| abstract | The invention relates to a photocatalyst of titanium dioxide and to a process for its production, used for the decontamination of contaminated waters with chlorinated organic pollutants. The photocatalyst according to the invention is in the form of thin, nanostructured titanium dioxide doped with 1.5 ... 6% sulfur, with a layer thickness of not more than 800 angstrom deposited on a silico-calco-sodium glass support or in the form of a powder with a crystalline size of not more than 350 angstroms, and exhibits photocatalytic activity in the visible field. The process according to the invention consists in contacting a solution of tetraethylorthotitanate and thiourea in absolute ethyl alcohol in a hydrolysis medium at a reaction temperature of 20 ... 50 ° C for a period of 60 ... 120 minutes , at a pH of 3 ... 5. Concentration of the precipitated solution at 80 ° C results in the catalyst being obtained as a powder. In the case of making the films, the hydrolysis process takes place in a closed system under a nitrogen atmosphere in the presence of a nitric acid catalyst; of the resulting clear solution is deposited two layers of films on the substrate by the immersion process, the second layer is applied after densification of the first layer at 300 ° C. |
