Due to more and more high rising buildings emerged in modern cities, photocatalytic<br />

materials especially titanium dioxide have been widely used as self cleaning materials.<br />

The aim of this research is to study the effect of calcination temperature and dopant<br />

to the TiO2. This study focuses on the rate of photodegrade on doped TiO2 and<br />

undoped TiO2 at different temperature. TTIP, acetic acid and ZnNO4 as dopant were<br />

used in synthesis of TiO2. The sample is characterized by using XRD, SEM and UV-VIS.<br />

Anatase phase formed at 500°C and anatase rutile mixed phase formed at 700°C. SEM<br />

shows that nanoparticles were obtained in the study. The degradation of MB under<br />

UV light of Zn-doped TiO2 is slightly higher than pure TiO2. The best temperature is at<br />

500°C and doped TiO2 is better than pure TiO2. This TiO2 was the highly stable and<br />

suitable as photocatalyst.
