Single-step synthesis of visible-light TiO(2-X)N(X) photocatalyst nanopowder by thermal plasma

Tsai C-Y, Hsi H-C, National Kaohsiung First University of Science & Technology, TW

In this study, TiO(2-X)N(X) was synthesized using transferred DC plasma torch as the heating source. As a result, the nanopowders of TiO(2-X)N(X) were formed via a single-step process. The formed TiO(2-X)N(X) nanopowder was characterized with [...]

Electrospun TiO2 Fibers as a Material for Dye Sensitizied Solar Cells

Duchoslav J., Rubáek L., Kavan L., Zukalová M., Procházka J., Elmarco Ltd., CZ

Electrospinning is a method for producing polymeric fabric with fibers ranging from 50 to 500 nm in diameter. It has been demonstrated that fibrous structure is preserved even after annealing when precursor of inorganic compound [...]

Synthesis of one-dimensional titanium dioxide nanostructures

Cottam B., Chyla S., Menzel R., Bismarck A., Shaffer M., Imperial College London, UK

Finely structured titanium dioxide is a technological material of long-standing importance for many applications including pigments and catalysis. There is growing interest in smaller, truly nano-sized titanium dioxide particles with well-defined crystallinity and a range [...]

Titanium Dioxide Nanostructured Coatings: Application in Photocatalysis and Sensors

Byrne J.A., Hamilton J.W.J., McMurray T.A., Dunlop P.S.M., Donaldson V.J.A., Rankin J., Dale G., Al Rousan D., University of Ulster, UK

This paper presents results concerning the fabrication, characterisation, and application of nano-structured titanium dioxide films. Applications include photocatalytic purification of water, “self-decontaminating” surfaces, and electrochemical biosensing.

Characterization on Dioxin Emission of TiO2 Nanoparticle-Encapsulating Poly(vinyl chloride) (TEPVC) compared to conventional PVC

Yoo H., Kim S-H, Lee A.R., Kwak S-Y, Seoul National University, KR

In our previous study, we first prepared TiO2 nanoparticle-encapsulating poly(vinyl chloride) (TEPVC) aiming at breakthrough to enhance the dispersibility of TiO2 nanoparticles in PVC matrix to maximize catalytic activities of TiO2 nanoparticles. The present study [...]

Stable Isotope Tracing – a way forward for Nanotechnology?

Gulson B., Wong H., McCall M., Danon S., Greenoak G., Trotter J., Casey P., Stauber J., Commonwealth Scientifc and Industrial Research Organisation, AU

Numerous publications and reports have expressed health and safety concerns about the production and use of nanoparticles, especially in areas of exposure monitoring, personal use, and environmental fate and transport. We suggest that stable isotopic [...]
