Sonochemical synthesis of Fe–TiO2–SiC composite for degradation of rhodamine B under solar simulator

Sonochemical synthesis of Fe–TiO2–SiC composite for degradation of rhodamine B under solar... Fe–TiO2–SiC composite with photocatalytic activity has been synthesized by a low cost sonochemical process in the presence of citric acid. The addition of citric acid during the sonochemical process allows the formation of a photocatalytic coating of Fe–TiO2 onto silicon carbide. Experimental characterization results indicate that the composite was formed over all the surface of the silicon carbide (SiC) with an anatase crystalline TiO2 phase with iron incorporation. The incorporation of iron narrows the band gap of TiO2 which allow the absorbtion of light with a large wavelength.

Abstract

Fe–TiO2–SiC composite with photocatalytic activity has been synthesized by a low cost sonochemical process in the presence of citric acid. The addition of citric acid during the sonochemical process allows the formation of a photocatalytic coating of Fe–TiO2 onto silicon carbide. Experimental characterization results indicate that the composite was formed over all the surface of the silicon carbide (SiC) with an anatase crystalline TiO2 phase with iron incorporation. The incorporation of iron narrows the band gap of TiO2 which allow the absorbtion of light with a large wavelength. The obtained Fe–TiO2–SiC composite exhibits good enhanced photocatalytic activity for the degradation of rhodamine B under solar simulator irradiation in comparison with the commercial TiO2–P25.
