TiO2 TiO2 TiO2 nanocomposite containing graphite carbon nitride and porphyrin compound and visible light-sensitive TiO2 photocatalyst containing the same

摘要

The present invention relates to a TiO 2 nanocomposite comprising graphite carbon nitride and a porphyrin compound and a visible light-sensitive TiO 2 photocatalyst comprising the same, and TiO 2 to which graphite carbon nitride (C 3 N 4 ) and a porphyrin compound are combined The nanocomposite exhibits photocatalytic activity in response to visible light, thereby exhibiting an excellent decomposition effect of contaminants by irradiation with visible light. In addition, since it is environmentally friendly, economical and exhibits excellent stability, it can be provided as a photocatalyst that can be used repeatedly.
