PREPARATION OF NANO FETIO3-TIO2 CATALYST FROM ILMENITE ORE FOR CATALYTIC DEGRADATION OF METHYLENE BLUE
Abstract
Nano FeTiO3-TiO2 promises as a highly effective material for photo catalytic degradation of organic dye pollutants. Nano FeTiO3-TiO2 has been successfully prepared from ilmenite ore as raw material by simple modified sulfate route. The obtained low cost iron titania possesses high active surface and good Fenton-like catalytic activity evaluated by monitoring the degradation of methylene blue (MB) in the present of H2O2. The effect of acid concentration during synthesis on crystal structure, composition of composites and catalytic activity of the prepared samples was investigated and discussed. The crystalline structure and morphologies of prepared samples was investigated with X-ray diffraction (XRD) and field emission scanning electron microscope (FE-SEM) coupled with EDAX, respectively. The adsorbed organic on samples surface were characterized by Fourier transform infrared spectroscopy (FTIR). The nano FeTiO3-TiO2 samples show significant effectiveness of catalyst under Fenton-like process due to the FeTiO3 content obtained from natural iron in ilmenite ore, sulphate group on samples surface and high surface area.
