Due to more and more high rising buildings emerged in modern cities, photocatalytic
materials especially titanium dioxide have been widely used as self cleaning materials.
The aim of this research is to study the effect of calcination temperature and dopant
to the TiO2. This study focuses on the rate of photodegrade on doped TiO2 and
undoped TiO2 at different temperature. TTIP, acetic acid and ZnNO4 as dopant were
used in synthesis of TiO2. The sample is characterized by using XRD, SEM and UV-VIS.
Anatase phase formed at 500°C and anatase rutile mixed phase formed at 700°C. SEM
shows that nanoparticles were obtained in the study. The degradation of MB under
UV light of Zn-doped TiO2 is slightly higher than pure TiO2. The best temperature is at
500°C and doped TiO2 is better than pure TiO2. This TiO2 was the highly stable and
suitable as photocatalyst.
