제목 W-TiO2 Nanopowders Synthesis and Photocatalysis
초록  Photocatalytic properties of TiO2 nanopowders has been received much attention due to their high potentials for environmental applications such as remediation of polluted environments. The TiO2 nanopowders doped with metal or non-metal elements have been synthesized by variety methods such as flame method, chemical vapor synthesis, sol-gel, ion implantation, which affect a doping behavior in  different ways resulting in different surface characteristics, leading to different photocatalytic activity. In addition to an effect of synthesis methods, the photocatalytic activity of TiO2 nanopowders can be improved by subsequent heat-treatments. In present study, we synthesized TiO2 nanopowders doped with tungsten by the chemical vapor synthesis method (CVS) and determined their photocatalytic activity, together with subsequent post-treatment in the range of 300℃ to 700℃.
