ZnO/AC　composites,　Fe2O3/AC　composites,　ZnFe2O4/AC　and　AC　blank　materials,　composites　were　prepared　by　In-situ　hydro-thermal　method　using　the　activated　carbons　as　supporter.　The　structure　and　properties　of　the　obtained　composite　were　characterized　by　scanning　electron　microscope　(SEM),　X-ray　spectrometer　(EDS),　X-ray　diffraction(XRD),Fourier　transform　infrared　spectroscopy(FT-IR),　physical　adsorption　instrument(BET)　and　X-ray　photo-electron　spectroscopy　(XPS)　analysis.　In　addition,　the　adsorptive　property　of　AC　was　tested　at　30℃　in　simulated　flue　gas.　The　results　showed　that　the　metal　oxide　compound,　as　an　active　component,　was　successfully　loaded　on　activated　carbons.　After　introducing　the　metal　oxide　compound,　the　specific　surface　area　pore　volume　decreased,　while　the　pore　diameter　increased,　and　the　SO2　adsorption　can　be　improved　significantly.　It　was　confirmed　that　desulphurization　efficiency　by　activated　carbon　loaded　with　ZnFe2O4　which　processed　a　high　specific　surface　area　of　435.9　m2/g,　entrance　of　0.37　cm3/g,　the　desulfurization　performance　test　sample　breakdown　in　the　time　of　136.0　min,　and　the　sulfur　capacity　of　168.3　mg/g,　in　comparison　to　the　AC,ZnFe2O4　and　other　composite　materials.　©　2018,　Chongqing　Functional　Materials　Periodical　Press　Co.　Ltd.　All　right　reserved.
