New Biological Pigments Findings from University of Osnabrueck Described [The visible light degradation activity and the photocatalytic mechanism of tetra(4-carboxyphenyl) porphyrin sensitized TiO2]

By a News Reporter-Staff News Editor at Life Science Weekly -- New research on Biological Factors is the subject of a report. According to news reporting out of Osnabruck, Germany, by NewsRx editors, research stated, "Tetra(4-carboxyphenyl) porphyrin(TCPP) were chemically sensitized on TiO2 to act as visible light antenna and to modify the photoresponse properties of TiO2 particles, their properties of photo-generated holes and electrons were studied by transient absorption spectroscopes. The time-correlated single-photon counting (TCSPC) technique revealed that the S2-S0 fluorescence intensity of TCPP is enhanced noticeably by TiO2, and the lifetime prolonged."

Our news journalists obtained a quote from the research from the University of Osnabrueck, "Adsorption and photo degradation of methylene blue (MB) over TCPP-TiO2 were systematically investigated. Moreover the overall picture of electronic relaxation dynamics for TCPP-TiO2 is presented, and the detailed short-time dynamics for visible-light induced catalytic mechanism was discussed."

According to the news editors, the research concluded: "The development of the porphyrin-based photocatalyst provides an alternative approach in harnessing solar visible light and show promising prospect for the treatment of dye pollutants from wastewaters in future industrial application."
