Abstract

The advanced method to produce nanoparticles of anatase mesoporous TiO? with high specific surface 300 m?/g has been developed. It was shown that titanium nanodioxide can be used in cement and gypsum composites as a highly efficient photocatalyst in the conversion processes of nitric oxide and volatile organic substances. Influence of radiation intensity, relative humidity, and concentration of contaminant and its stream speed on photocatalysis was studied. It was determined that efficiency of the composites with synthesized samples is 1,5?1,7 times higher than that of the commercial sample of the titanium nanodioxide.
