enhanced photocatalytic disinfection of escherichia coli bacteria by silver and nickel comodification of a nitrogen doped Titanium Oxide Nanoparticle photocatalyst under visible light illumination
Journal of the American Ceramic Society, 2010Co-Authors: Caixia Sun, Shian Gao, Lihua Cao, Jian Ku ShangAbstract:Enhanced photocatalytic disinfection of Escherichia coli bacteria under visible light illumination was achieved by introducing silver and nickel comodification onto a nitrogen-doped Titanium Oxide Nanoparticle photocatalyst synthesized by the sol-gel process. The introduction of a small amount of the second-type transitional metal ion addition is demonstrated as an effective approach to further enhance the optical and photocatalytic properties of single-type transitional metal ion modified anion-doped Titanium Oxide photocatalysts.

as iii removal by palladium modified nitrogen doped Titanium Oxide Nanoparticle photocatalyst
Environmental Science & Technology, 2009Co-Authors: Nickolas Joseph Easter, Jian Ku ShangAbstract:Removal of arsenic species from water by palladium-modified nitrogen-doped Titanium Oxide (TiON/PdO) Nanoparticles was investigated with and without visible light. For the first time, a high degree of As(III) removal under visible light illumination was demonstrated on Oxide photocatalysts. Over 2 orders of magnitude decrease of As(III) concentration in water was observed in 1 h as the As(III) concentration was reduced below the U.S. Environmental Protection Agency standard (10 μg/L) by TiON/PdO photocatalyst. Such an efficient removal of As(III) was shown to result from the combined effects of strong adsorption and photooxidation by TiON/PdO, where an enhanced photocatalytic activity under visible light illumination than nitrogen-doped Titanium Oxide (TiON) was derived from the strong optoelectronic coupling between PdO and TiON.

Titanium Oxide Nanoparticle dispersions in a liquid monomer and solid polymer resins prepared by sputtering
New Journal of Chemistry, 2016Co-Authors: Matteo Porta, Tomoharu Tokunaga, Yohei Ishida, Hiroki Tsukamoto, Yuichi Shishino, Tetsu Yonezawa, Mai Thanh Nguyen, Yoshikiyo HatakeyamaAbstract:A transparent resin containing Titanium Oxide Nanoparticles (NPs) was prepared using a molten matrix sputtering (MMS) technique. The low vapour pressure of the liquid, pentaerythritol ethoxylate (PEEL) substrate permits the use of this vacuum technique directly with liquid PEEL under stirring conditions in order to obtain uniform dispersions of NPs. We found that it is possible to synthesize Titanium Oxide, TiOx, NPs with diameters of less than 5 nm with a controlled composition by simply adjusting the sputtering atmosphere. Furthermore, as the electronic structure of the TiOx NPs changes depending on the particle size, crystallinity and degree of oxidation, we were able to modify the optical properties of PEEL and the resin by embedding TiOx NPs in the matrix. The enhancement of the refractive index of a resin containing TiO2 NPs was also demonstrated. This synthetic method is promising for the advanced preparation of high purity TiOx NPs without using a reducing agent and leaving by-products for various applications in optical devices, energy conversion, and light harvesting in the UV visible region.
