Reduced graphene oxidehybridized TiO2 for visible-light photocatalytic degradation of phenol in drum-type photo-catalytic reactor
摘要
Abstract
Reduced graphene oxide hybridized TiO2 was prepared by hydrothermal synthesis method and its physico-chemical properties were analyzed by Scanning electron microscope(SEM),transmission electron microscope(TEM),X-ray diffraction(XRD)etc.Epoxy resin(E-44)and polyamide resin as binder,catalyst powder was anchored on the surface of quartz drum successfully by two-steps anchored method.Drum-type photo-catalytic reactor was employed to degrade the phenol solution under visible light.The spherical TiO2 nanoparticles(diameter 20～50 nm)were anchored on rGO sheets and dispersed well.TiO2/rGO nanocomposites revealed a higher specific surface ar-ea and electron mobility,lower recombination probability between electrons(e)and holes(h+)and red shift of ad-sorption into the visible region,which are in favor of high photocatalytic activity under solar light(xenon lamp).When the rotate speed and cyclic solution flow rate were 20 r/min and 30 mL/min with xenon lamp irradiation,the degradation rate of phenol reached the top of 90%,which provided a novel way for the degradation of organic pollu-tion and solved catalyst recovery problem.关键词
