Photodegradation of organic compounds using TiO2-based impregnated photocatalysts

The photodegradation of organic compounds in water solutions using environment-friendly materials, methods and processes is a topic of growing interest. A great interest regarding this subject has been devoted to TiO2-based photocatalysts for the oxidative photodegradation of various organic pollutants. In this context, some photocatalytic polycrystalline TiO2 systems impregnated with metalloporphyrins were prepared. The metalloporphyrins used for impregnation were prepared in agreement with the scientific literature. After impregnation, the TiO2-based photocatalysts were investigated for their photoactivity in the oxidation reaction of organic compounds. A comparison of the photoreactivity of the newly obtained catalytic materials was made.
