Researches of visible light photo-sensitized porphyrin-TiO2 photocatalyst and its related self-cleaning effects

Min K., Manivannan R., Lee S-G, Son Y., Chungnam National University, KR

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, [...]

Mimicking Photosynthesis to Make Functional Nanostructures and Nanodevices

Shelnutt J.A., Wang Z., Song Y., Medforth C.J., Pereira E., Sandia National Laboratories, US

Photocatalytic porphyrins are used to reduce metal complexes from aqueous solution and, further, to control the deposition of metals onto porphyrin nanotubes and surfactant assembly templates to produce metal composite nanostructures and nanodevices. For example, [...]

Self-Assembly of TPPS4 Porphyrin Molecules into Nanorods Investigated by TEM, AFM, STM and UV/VIS Spectroscopy

Snitka V., Rodaite R., Mizariene V., Kaunas University of Technology, LT

In this work the aggregates of the tetrakis(4-sulfonatophenyl)porphyrin (TPPS4) growth from solution on solid crystalline hydrophilic and hydrophobic substrates were investigated. The spatial structure of TPPS4 deposited on the surface was imaged using Transmission Electron [...]
