Abstract

Sets of Fe-Ti/hydrotancite materials are hydrotanxite samples modified by Fe^{3 +} and Ti^{4 +}, synthesized by co-precipitation method. The precursors Al(NO₃)₃.9H₂O, Zn(NO₃)₂.6H₂O, Fe(NO₃)₃.9H₂O, tetraisopropyl octotitanate (TIOT) and Na₂CO₃ are used to synthesize the samples. Synthetic materials characterized by many modern physical analysis methods: XRD diagrams, TEM images, UV-Vis DRS spectra. Photocatalytic activity of synthetic materials was assessed through the ability to degrade rhodamine-B in water. The survey results have selected the sample of FeTiH-0.1 (M1.2) material with the highest activity under the light LED 30 W of Rang Dong company, Viet Nam.

Keywords
