The photodegradation effect of organic dye for metal oxide (Cr 2O3, MgO and V2O3) treated CNT/TiO2 composites

Abstract

Three kinds of organometallic compounds (chromium acetylacetonate, magnesium acetate and vanadyl acetylacetonate) were used as transition metal precursor, titanium n-butoxide and multi-walled carbon nanotube as titanium and carbon precursor to prepare metal oxide-CNT/TiO2 composites. The surface properties and morphology of metal oxide-CNT/TiO2 composites were by Brauer-Emett-Teller (BET) surface area measurement, scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD) and energy dispersive X-ray (EDX) analysis. The photocatalytic activity of prepared metal oxide-CNT/TiO2 composites was determined by the degradation effect of methylene blue in an aqueous solution under irradiation of visible light.
