One of the reported doping agent to increase TiO2 activity is Cu. In this research, TiO2 was prepared by So-Gel method. Preparation was performed by calcinaton at the temperature range of 400, 500, 600°C for 2 hours with a corresponding dopan concentration of 0%, 1%, 3%, 5% mol of TiO2. The nanoparticle materials was characterized using XRD. It is found that anatase phase occur in the calcinations temperature of 400°C and transform to rutile phase at 500°C. The crystallite size of Cu-doped TiO2 with dopan concentration of 5% are found 4.63 nm, 8.70 nm, 6.09 nm respectively at 400°C, 500°C, 600°C. © 2019 Published under licence by IOP Publishing Ltd.
