$aTitanium dioxide (TiO2) and derivatives are considered to be among of the most promising materials for solving the environmental and energy issues due to their high photochemical activity, stability, safe and low cost. The strong photocatalysis of TiO2 has been used and proposed for destruction of pollutants, anti-bacterial, self-cleaning, gas sensor, water photolysis and photovoltaic but its efficiency need to be further improved. Enlarge the specific surface area by using nanostructures and modify the band gap by hybrid materials to shift the photocatalysis into the visible range are being proposed as effective approaches. With respect to the viewpoints of thermodynamic considerations, the thermolysis of Ti precursors will initiate the formation of tiny anatase nanocrystalites and follow with crystal growth process. By controlling the synthesis conditions, anatase nanostructure with desirable size is achieved and can be used for improvement of photocatalytic feature. In this work, photocatalystic properties as well as formation of TiO2 nanostructure synthesized by thermolysis is presented and discussed.
