%X TiO2/SWCNT nanocomposite has been successfully synthesized by the sol-gel method. Single-walled carbon nanotubes (SWCNT) functionalized with acid. TiO2/SWCNT composite was coated on the cork with a dip-coating technique. The crystal structure, morphology, and physicochemical properties of the composites were characterized by FTIR, XRD, SEM-EDX, SEM mapping, and UV-Vis spectra. FTIR data obtained functional groups of TiO2 and carbon. XRD test shows the crystal structure and shape of the nanoparticle material. SEM test was found that TiO2 was firmly attached to the sidewall of the SWCNT. The performance test of TiO2/SWCNT composite was evaluated by monitoring the degradation rate of methylene blue (MB) under a solar simulator. There was a significant decrease in the concentration of methylene blue (MB) when TiO2/SWCNT composite coated on the cork was added. After degradation for 2 hours, the results of the effectiveness of TiO2/SWCNT composite are approximately 99. The photocatalytic activity of the TiO2/SWCNT nanocomposite in this experiment was influenced by the different compositions of TiO2 and SWCNT, the method used, the success of coating on the cork and light from the solar simulator. © 2023 Author(s).
