Abstract:
A method for the preparation of a SiO2–TiO2/Cr2O3(840) porous composite material in a block form with walls made of a silicate matrix and the interconnected channels of the matrix containing TiO2/Cr2O3(840) spherical hollow oxide composites was proposed. The specific surface area (Ssp) of the block composites was 212.2 m2/g, which is 20 times greater than the value of Ssp for spherical composites not fixed in the silicon(IV) oxide matrix. The composition of the TiO2/Cr2O3(840) and SiO2–TiO2/Cr2O3(840) samples was studied by X-ray diffractometry and X-ray microanalysis, which indicated the presence of chromium(III) oxide, titanium(IV) oxide, and an amorphous silicon(IV) oxide phase in the latter. The SiO2–TiO2/Cr2O3(840) block composite material exhibited catalytic activity in the deep oxidation reaction of para-xylene: a 100% conversion of the organic substance was achieved at a temperature of 350°C. © 2019, Pleiades Publishing, Ltd.
