| Abstract |
The sensitization of TiO2 with a wide variety of inorganic and organic dyes for light harvesting has been investigated over the last 2 decades for the development of efficient energy harvesting. Porphyrins, as important biomolecules, have some applications such as catalysts, photosensitizers, non-linear optical materials, liquid crystal, photodynamic therapy of cancer, solar-energy conversion, molecular binding, energy and electron transfers and light harvesting. Silyl derivatives are generally hydrophobic in nature; by incorporating all these properties to a fabric self-cleaning properties were investigated. A super hydrophobic PET fabric exhibiting photocatalytic self-cleaning properties under visible-light was prepared by step-wise deposition of anatase TiO2, and 5 types of porphyrin. The OTMS/Porphyrin/TiO2 modified PET fabrics showed significant photo-degrading of rhodamine dye molecule not only under UV-light but also under visible light.
