The development of TiO2 based catalyst for poisoning organic molecules removal

Abstract

This research aims to study a synthesis of the Titanium dioxide (TiO2) as a photocatalyst which is loading onto a pineapple leaf fiber (TiO2/PF) by using hydrolysis method and heating with autoclave, and using succinic acid as a crosslink molecules. The researchers conduct the experiment to compare to use and non-use sodium hydrogen phosphite (NaH2PO2) as a catalyst support. Afterwards, we verifies the attribute and property of the catalyst which has been through the x-ray diffraction (XRD), the Fourier transform infrared spectroscopy (FTIR), scanning electrons microscopy (SEM) the thermal gravimetric analysis (TGA) and determination of TiO2 deposited on PF. Determination pf Ti on catalyst using Inductively coupled plasma atomic emission spectroscopy (ICP-OES). The activity of the catalyst could experiment by testing the degradation of a methylene blue using UV-vis spectrophotometer under UV irradiation at 664 nm. The study demonstrate that the catalyst TiO2/PF which uses Succinic acid as a crosslink molecule and using NaH2PO2 as a catalyst support could provide the degradation of a methylene blue to be the most efficient way rather than non-using the catalyst.
