Abstract: Recently, the photocatalytic activity of titania has attracted considerable attention for solving various environmental problems. Photocatalysis is considered to be effective in air purification, water purification, and used for dealing with various types of environmental pollution. The smaller the particle size of titania, the faster the photocatalysis proceeds. Since our previous study revealed that the modification of synthesis process reduced the particle size of silica, we attempted to apply this process to synthesise titania, with an objective of obtaining titania with high photocatalytic activity. This paper describes an unconventional gas-phase synthetic method involving high-temperature hydrolysis.

Keywords: titania particles; fine powder; photocatalysis; gas phase synthesis; environmental engineering; photocatalytic activity; high temperature hydrolysis; environmental pollution; TTIP; titanium tetraisopropoxide.
