【 摘 要 】

The synthesis of TiO2together with the TiO2-NiO composite using various annealing temperatures has been studied. The synthesis of TiO2was performed by sol gel method using Titanium Tetra Isopropoxide (TTIP) precursor, whereas the synthesis of TiO2-NiO composite was done by wet impregnation method using NiNO3.6H2O precursor. This study aims to determine the influence of NiO addition in its structure and photoactivity. The diffraction of synthesized TiO2at 400 °C temperature shows anatase TiO2peak at 2θ = 25.35 °. The addition of NiO dopant to the synthesis of TiO2process is carried out by annealing at 300 °C, 400 °C, 500 °C, 600 °C, and 700 °C, respectively. The TiO2-NiO composite has been prepared and shows the diffraction peak of NiO at 2θ=43° about 33.08 to 36.68%. The optimum result of Rhodamine B photodegradation with TiO2was 43.15%, while the optimum result of Rhodamine B degradation with TiO2-NiO composite was 92.85%.
