Description:
The photocatalyst technology is an integrated combination of photochemical processes and catalysis in order to carry out a chemical transformation reaction. One of the semiconductor materials that have good photocatalytic activity is TiO 2 anatase. This study aim to determine the effect of the Cr 3+ addition on the growth of TiO 2 rutile crystal and the increasing of TiO 2 photoactivity. Diffractogram X-Ray of the samples showed that the synthesized TiO 2 at 400 °C has been produced 100% TiO 2 anatase. Synthesis of TiO 2 doped Cr 3+ composite was using wet impregnation method. The TiO 2 doped Cr 3+ composites have beed grown by annealed at a temperature of 300, 400, 500, 600 and 700 °C, respectively Annealing process have capabled to gain to the TiO 2 doped Cr 3+ nanocomposite. The result product annealed at 500 °C only appear anatase phase due to the Cr 3+...
