Findings on Biological Pigments Reported by Investigators at City University of Hong Kong (Exploring the Use of Dye-Sensitisation by Visible-Light as New Approach to Self-Cleaning Textiles)

By a News Reporter-Staff News Editor at Life Science Weekly -- Investigators discuss new findings in Biological Factors. According to news reporting out of Hong Kong, People's Republic of China, by NewsRx editors, research stated, "Photocatalytic degradation of organic Contaminants by self-cleaning textiles is an efficient method to create green environment and minimise energy consumption. In this work, the concept of dye-sensitised self-cleaning textiles has been introduced by incorporating monolayers of meso-tetra(4-carboxyphenyl)porphyrin (TCPP) on the surface of titania-coated cotton against methylene blue."

Our news journalists obtained a quote from the research from the City University of Hong Kong, "Different complexes of TCPP (M = 2H, Fe, Co, Zn, Cu) have been trialled and evaluated for photocatalytic activity and stability. Cotton fabrics coated with TCPP show superior photochemical activity as compared to TiO2-coated fabrics under visible-light irradiation. The free base derivative availed the highest photocatalytic efficiency when compared to the metal complexes with Cu similar to Fe >Co >Zn. In terms of stability, meso-tetra(4-carboxyphenyl)porphyrinato copper(II) showed significant stabilisation under photocatalytic conditions when compared to the metal-free porphyrin and other metal complexes (Cu >> Co > 2H > Zn similar to Fe)."

According to the news editors, the research concluded: "Porphyrins offer great potential in visible-light self-cleaning applications."
