HEPTAZINE-MODIFIED TITANIUM DIOXIDE PHOTOCATALYST AND METHOD FOR THE PRODUCTION THEREOF

摘要

The invention relates to a photocatalyst comprising heptazine on the basis of titanium dioxide that is photoactive in the visible region and to a method for the production thereof. The novel photocatalyst enables a degradation of pollutants not only by way of artificial visible light, but also by way of the diffuse daylight in interiors. The novel photocatalyst is produced such that titanium oxide having a specific surface of at least 30 m2/g is mixed with a heptazine derivative or an oligo-heptazine derivative. The mixture is thermally treated at a temperature of approximately 300°C to 500°C.
