Effect of Synthesis Temperature on Photocatalytic Activity of TiO2 Nanoparticles Prepared via Solvothermal Method

In this research, the effect of synthesis temperature on the phase composition, crystal size, morphology and photocatalytic activity of titanium dioxide nanoparticles prepared by solvothermal method was investigated. The results showed that the crystallinity of the particles occurs within the gel-like matrix and the particles size increases from 4 to 8 nm by increasing the synthesis temperature. All samples showed suitable photodegradiation up to 94% yield. Nano-particles synthesized at 120°C showed the highest photocatalytic activity.
