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, [...]

Synthesis of Visible light Nanocomposites for H2 Production

Hussein A.M., Shende R.V., South Dakota School of Mines & Technology, US

Visible light active nanocomposites were synthesized by the sol-gel method using non-ionic surfactant as a template. Cr-doped ZrO2-modified coupled ZnO/TiO2 composite was thoroughly characterized for surface area, crystal phase, microstructure, elemental identification and band gap [...]

Photocatalytic activity of mesoporous titanium dioxide nanoparticles under visible light irradiation

Ikuma Y., Kida S., Kuramoto R., Niwa K., Anandan S., Kanagawa Inst. of Tech., JP

Using surfactant and other chemicals, nano-template consisting of SiO2 was first prepared. Then the template was treated in titanium tetra-isopropoxide dissolved in 1-propanol to convert silicon into titanium. The product was heated in air or [...]

The Characteristics and Photocatalytic Activity of Visible Light Driven N-doped TiO2

Hsu H-J, Lin Y-H, Lin Y.-T., Lin Y-H, Lin Y.-T., National Chung Hsing University, TW

In the recent decades, titanium dioxide (TiO2) nano-material was received widely attention because of its good chemical stability, low-toxicity, self-cleaning, anti-bacteria and deodorant. However, its photocatalytic activity was limited only by ultraviolte (UV) light irradiation [...]
