METHOD OF PRODUCING CATALYST FOR CLEANING WATER FROM HYDROCARBON CONTAMINANTS Russian patent published in 2013 - IPC B01J23/04 B01J21/06 B01J23/50 B01J37/00 C02F1/32 B82B1/00 

FIELD: chemistry.

SUBSTANCE: invention relates to chemical industry and specifically to methods of producing highly efficient catalysts which are capable of cleaning water from hydrocarbon contaminants, particularly basic dyes and cationic surfactants due to photocatalytic activity under the effect of solar radiation as well as in the dark. Described is a method of making a titanate catalyst, which involves reaction of an alkali metal titanate, having a layered structure, with a medium which contains a dopant, separating the protonated product from the solution and heat treatment thereof, wherein the alkali metal titanate used is potassium titanate, having a lepidocrocite layered structure; the medium which contains a dopant used is an aqueous solution which contains a water-soluble silver salt and has pH≥5.6; and heat treatment is carried out at temperature in the range of 70-120°C.

EFFECT: high adsorption capacity of the catalyst, high photocatalytic activity in the visible spectrum and capacity to support catalytic decomposition of hydrocarbons in complete darkness, which significantly broadens the capabilities for use thereof in industrial treatment systems.
