Solution Grown Nanostructured Ceramic Coatings for Photocatalytic and Antibacterial Surface

Tao T., Cho J., Binghamton University, US

Ceramics coatings have received great attention for use as a functional surface, as well as a protective and barrier coating. We report a low-temperature hydrothermal processing of nanostructured ceramic coatings that enable their surface to [...]

Preparation of Photocatalytic Silicon Core-shell Nanoparticles Covered by ZnS Shell in Solid-Gas Reaction

Dvorsky R., Praus P., Svoboda L., Matýsek D., Dropa T., Trojková J., Šollová K., VŠB-Technical University of Ostrava, CZ

For easy handling in some practical processes, active nanoparticles are usually deposited on surfaces of larger carrier particles. In our previous work, the particles of montmorillonite MMT with a mean size of 300 nm served [...]

Photocatalytic disinfection of E. coli using tourmaline-N-doped TiO2 composite

Tzeng J-H, Lin Y.-T., Weng C-H, National Chung Hsing University, TW

Neither the microbicidal mechanism of TiO2 under visible radiations nor their potential effects in the light intensity have yet been well established. In this paper, the photocatalytic inactivation of bacteria was investigated using E. coli, [...]

Photocatalytic Silver/Silver Halide Polymer Nanocomposites

Tate E., Johnston J.H., Victoria University of Wellington, New Zealand, NZ

Recently it has been shown that hybrid silver/silver halide nanoparticles exhibit interesting photocatalytic properties, and are known plasmonic photocatalysts. Enhanced photostability and photocatalysis are observed in the nanoparticles due to the surface plasmon resonance of [...]

Study of Photocatalytic activity and properties of Transition metal ions doped Nanocrystalline TiO2 prepared by Sol-Gel Method

Siddhapara K., Shah D., S.V. National Institute of Technology, IN

In summary, we have reported the synthesis of 1%, 2% and 4% Fe,Co doped TiO2 powders successfully prepared via sol–gel synthesis and controlled calcinations. XRD for Fe, CO doped TiO2 indicates dopant concentration effects phase [...]

Enhancement of Photocatalytic Cancer Cell-Killing Activity by Using Ag@TiO2 Core-Shell Composite Nanoclusters

Abdulla-Al-Mamun M., Yang H., Kusumoto Y., Kagoshima University, JP

The photocatalytic cancer cell-killing activities of the Ag@TiO2 core-shell composite colloidal nanoclusters have been investigated on HeLa cells killing under the UV-visible light irradiation. The Ag metal core-TiO2 shell (Ag@TiO2) composite nanocluster photocatalyst with uniform [...]
