THE EFFECT OF DIFFERENT TYPES OF SOLVENTS ON MORPHOLOGY OF CARBON-MODIFIED TIO2/H-ZSM-5 COMPOSITE

Abstract

This study aims to investigate the effects of different solvents (isopropanol, benzene, and toluene) on the synthesis of carbon-modified TiO2/H-ZSM-5 composites. Carbon-modified TiO2/H-ZSM-5 composites were characterized by FTIR, XRD, and SEM. XRD analysis revealed that the TiO2 peaks at 2 = 25.3, 37.8, and 48.2° had distinct characteristics. FTIR analysis revealed that I-ZTC, B-ZTC, and T-ZTC had comparable absorption bands to ZSM-5 at 3464, 1639, 1222, 1097, and 545 cm-1, respectively. Additionally, the FTIR data revealed that I-ZTC, B-ZTC, and T-ZTC all display absorption bands around the wavenumber 450 cm-1, indicating the Ti-O bond's stretching vibration. Additionally, SEM-EDX analysis revealed that Ti was more evenly distributed on the surface of T-ZTC than on the surfaces of B-ZTC and I-ZTC. It was shown that the solvent's polarity has an effect on TiO2 dispersion. A less polar solvent disperses TiO2 more effectively. In terms of TiO2 dispersion, toluene was the preferable solvent for the production of carbon-modified TiO2/H-ZSM-5.
