Abstract

This study aims to synthesized and characteried TiO2-zeolite composite synthesised and evaluate the effect of varying of TiO2-zeolite composition as photocatalys for the degradation of methyl orange. Zeolite was activated by HCl treatment, and TiO2-zeoliet composites were synthesized using the impregnation method and characterized by XRF and XRD. For the composition variations, 3.000 g of zeolite was kept constant, while the amount of TiO2 was varied at (g) 0.1500, 1.0125, 1.875, 2.7375, 3.6000, respectively. The degradation test of methyl orange was measured using using a UV-Vis Spectrophotometer at a wavelength of 463 nm. XRF characterization showed that zeolite activation increased the Si/Al ratio. XRD analysis of the zeolite revealed a diffraction pattern consistent with mordenite. In the TiO2-zeolite diffraction pattern, a new peak corresponding to the typical anatase phase with a tetragonal structure was observed, indicating succesful synthesis of the TiO2-zeolite composite. UV-Vis spektrofotometer analysis demonstrated that the TiO2-zeolite composite achieved optimum degradation efficiency of 98.28% at the 3.0000:1.875 composition.
