Colloidal TiO2 nanocrystals/MEH-PPV nanocomposites: Photo(electro)chemical study

Article Abstract:

A study presents an extensive optical and photoelectrochemical investigation of blended systems composed of organic-capped TiO2 nanocrystals with either a spherical or rodlike morphology and a conjugated polymer, MEH-PPV. The investigation is focused on the photoinduced charge transfer and recombination process at the interface between the two components, as a function of the nanocrystal shape and surface coating, and of film thickness.

Role of metal nanoparticles in TiO2/Ag nanocomposite-based microheterogeneous photocatalysis

Article Abstract:

A study was conducted, during the reductive bleaching of a model dye called Uniblue A (UBA), to investigate the photocatalytic performance of anatase TiO2 nanorod-stabilized Ag nanoparticles in homogeneous organic solutions. The result revealed that the photocatalytic activity of the TiO2/Ag nanocomposite under steady-state irradiation could vary continuously during the course of photocatalysis.

ZnO nanocrystals by a non-hydrolytic route: Synthesis and characterization

Article Abstract:

A novel, non-hydrolytic route to ZnO nanocrystals by means of thermal decomposition of zinc acetate (Zn/Ac(sub 2)) in alkylamines, in the presence of tert-butylphiosphonic acid is reported. The synthesis provides a unique tool for designing the synthesis of ZnO crystals of a desired size in the nanoscale regime and can be potentially to other nanoscale materials.
