TiO<sub>2</sub> in the absence and presence of AC were prepared by the sol-gel method. TiCl<sub>4</sub> was used as a precursor to reduce using acidic solution during preparation process. The effects of the amount of AC on the characteristics of composites were investigated. TGA technique was used to evaluate the amount of TiO<sub>2</sub> and AC in TiO<sub>2</sub>/AC composite. The adsorption properties of TiO<sub>2</sub>/AC were characterized using XRD, TEM, N<sub>2</sub> adsorption/desorption, FTIR and UV–Vis diffuse reflectance spectroscopy techniques. The photocatalytic activities of the composites were investigated by measuring the removal of acid dye. Results showed that the specific surface area of TiO<sub>2</sub>/AC increased with increasing mass fraction of AC, while the energy band gap was reduced. It was clearly shown that TiO<sub>2</sub> in the presence of AC produced a synergistic effect of the composite and led to an increase in photocatalytic performance. Also, the reuse of TiO<sub>2</sub> with 20% AC nanocomposites for dye removal showed a high reuse efficiency above 90% in photocatalytic dye degradation.</p>}, number={4}, journal={Journal of Metals, Materials and Minerals}, author={Chobchun, Mark and Jutakridsada, Pasakorn and Thiamsinsangwon, Puttiporn and Kasemsiri, Pornnapa and Kamwilaisak, Khanita and Chindaprasirt, Prinya}, year={2020}, month={Dec.}, pages={30–38} }
