Effect of addition octadecyltrimethoxysilane (OTMS) on morphology ZSM-5-TiO2 composite
ZSM-5-TiO2 composites are usually used as adsorbents as well as photocatalyst in waste treatment. However, these composites are less effective insoluble waste treatment, so it needs to modify by adding organic substances that can react with the waste. In this study, Octadecyltrimethoxysilane (OTMS)...

| Summary: | ZSM-5-TiO2 composites are usually used as adsorbents as well as photocatalyst in waste treatment. However, these composites are less effective insoluble waste treatment, so it needs to modify by adding organic substances that can react with the waste. In this study, Octadecyltrimethoxysilane (OTMS) was added to the surface of the ZSM-5-TiO2 composite. The effect of addition OTMS on morphology ZSM-5-TiO2 composite was studied. ZSM-5-TiO2-OTMS composite was characterized by X-Ray Diffraction (XRD), Fourier Transformation Infrared Spectroscopy (FTIR), and Energy Dispersive X-ray Scanning Electron Microscopy (SEM-EDX). ZSM-5-TiO2-OTMS shows a carbon-related peak at 2900 and 1470 cm-1 that can be ascribed as C-H stretching and C-O stretching vibration respectively from FTIR spectra. ZSM-5-TiO2-OTMS composite retains the hexagonal shape surrounded by round-shaped. The addition of OTMS affects the morphology of the ZSM-5-TiO2 composite. The more OTMS is added, the morphology of the ZSM-5-TiO2-OTMS composite to be more irregular than composite ZSM-5-TiO2. It also affects the amount of carbon content that is distributed on the surface of the ZSM-5-TiO2 composite. This provides information material that can be used in synthesize catalysts in the insoluble waste treatment. |
