Synthesis, Characterization of Hybrid Aluminosilicate Material for Photocatalytic Application

Abstract

Titanium prepared ferric diatomite modified composite as catalyst and characterized in this study.The titanium prepared ferric diatomite modified called “ TDF ” was made a surface modification treatments including Iron ( III ) nitrate nanohydrate Fe(NO3)3.9H2O then titanium dioxide TiO2 degussa P25 deposition on raw diatomite .In the Fe(NO3)3.9H2O treatment, surface silica of diatomite and TiO2 degussa P25 were partially dissolved in The iron ( III) nitrate nanohydrate Fe(NO3)3.9H2O by means of x-ray fluorescence ( XRF ), scanning electron microscopy ( SEM ), thermogravimetric analysis ( TGA ), differential scanning calorimetry ( DSC ), and UV-visible diffuse reflectance spectroscopy ( DRS ).The surface area of TDF is 855 m2/g.The surface modification also increased the point of zero charge ( pHPZC ) values to 6 for titanium prepared ferric diatomite modified “ TDF ” with gap band was Eg= 1.1 eV by UV-visible DRS technique
