Özet

In this study, the thermal catalytic powder mixtures of Mn, Ce and Co oxides supported on AL(2)O(3) were synthesized. In order to obtain thermally active porous coating on the steel substrate, a binder solution produced via sol-gel method was used to bind the synthesized powder. Additionally by incorporation of TiO2 nanoparticles to previously described thermally active coating, both thermally and photocatalytically active multifunctional surfaces were obtained. The self-cleaning property and the rate of volatile organic compounds (VOC) degradation of the coatings were studied, in which pyrazine, thiazole, maltol, vanillin and toluene were applied as VOC. In TiO2 applications UV illuminations were applied. In the self-cleaning performance tests using soybean oil, the thermally active coating was slightly better than the TiO2 containing coatings. Under UV illumination, the high rates of VOC (photo) degradation was achieved with the thermally and photocatalytically active coating.
