Abstract

Spindleshaped microstructure of αFe2O3 was successfully synthesized by a simple hydrothermal method The αFe2O3/graphene oxide GO composites was prepared using a modified Hummers’ strategy The properties of the samples were systematically investigated by Xray powder diffraction XRD UV–Vis diffuse reflectance spectrophotometer transmission electron microscope atomic force microscope Xray photoelectron spectroscopy and Raman spectroscopy Raman techniques GO nanosheets act as supporting materials for anchoring the αFe2O3 particles The average crystallite sizes of the αFe2O3 and αFe2O3/GO samples are ca 27 and 24 nm respectively The possible growth of αFe2O3 onto GO layers led to a higher absorbance capacity for visible light by αFe2O3/GO than αFe2O3 composite The photocatalytic degradation of toluene over the αFe2O3 and αFe2O3/GO samples under xenonlamp irradiation was comparatively studied by in situ FTIR technique The results indicate that the αFe2O3/GO sample synthesized exhibited a higher capacity for the degradation of toluene The composite of αFe2O3/GO could be promisingly applied in photodriven air purificationThis work was supported financially by the National Nature Science Foundation of China NSFCRGC 21061160495 and No 21207015 the National High Technology Research and Development Program of China 863 Program No 2010AA064902 the Major State Basic Research Development Program of China 973 Program No 2011CB936002 the Excellent Talents Program of Liaoning Provincial University LR2010090 and the Key Laboratory of Industrial Ecology and Environmental Engineering China Ministry of Education
