PP-19 Неорганические композитные мембраны SiO2, TiO2/нержавеющая сталь с включением Ni-соли молибденфосфорной гетерополикислоты SiO2 and mixed TiO2-SiO2 composite membranes have been prepared on macroporous stainless steel support using sol-gel method. Ni salt of 12-molybdophosphoric heteropoly acid has been introduced in the top layer by coating from aqueous solution and coprecipitation with TiO2 sol. Composite membranes with different pore sizes and surface areas could be regulated by various concentration of used sols and multiple deposition. Thiophene conversion is three times higher on the membrane prepared by coprecipitation in comparison with one prepared by dipping coating of heteropoly compound.
