Abstract
Abstract The research analyzed the physical properties of TiO 2 and bentonite nanocomposite as adsorbent materials. The TiO 2 synthesis method was carried out through a sol–gel process. Meanwhile the synthesis of bentonite was carried out by the ball mill, coprecipitation and addition of cetyltrimethylammonium bromide (CTAB) surfactant. X-ray diffraction nanocomposite characterization showed that the particle size was 17.13 nm. Fourier transform infrared analysis showed the required absorption peak in photocatalysis because the OH group can react with holes and prevent electron–hole pair recombination. The morphology of the nanocomposite showed the occurrence of TiO 2 pillarization in bentonite. The results of the X-ray fluorescence nanocomposite showed that the content of TiO 2 and SiO 2 was 65.22 and 17.4%, respectively.
