dcterms:description
Kaolinite/TiO2 (KATI) and quartz/TiO2 (SITI) composites with 20 wt% of TiO2 were prepared by the suspension hydrolysis of titanylsulphate (TiOSO4) in the presence of both carriers (kaoline and quartz). Obtained composites were thermally modified at the 600 °C. In the case of the KATI composite the dehydroxylation of kaolinite structure leads to metakaolinite formation at temperatures higher than 500 °C, so obtained composite shows photocatalytical properties as well as also latent hydraulic properties. The SiO2 matrix does not undergo any changes during calcination of the SITI composite and this composite serves as indifferent photoactive filler. All the prepared composites were studied by X-ray fluorescence spectroscopy (XRFS), X-ray powder diffraction analysis (XRPD) and scanning electron microscopy (SEM). Their photodegradation activity evoked by the 1 hour of irradiation using UV lamp with maximum at 365 nm was determined by the means of discoloration of acid orange (AO7) solution.
