摘      要：Fe-loaded activated carbon(AC)has high surface acidity and more active sites,while manganese-loaded AC has high oxygen *** husk AC modified by Fe-Mn was studied with the aim of revealing the modification ***,HNO_(3)AC was prepared using the nitric acid immersion ***,Fe-Mn/AC was prepared using the Fe(N0_(3))_(3)and Mn(N0_(3))_(2)sequential *** effects of HNO_(3),Fe(N0_(3))_(3),and Mn(N0_(3))_(2)on the pore texture and surface chemical characteristics of carbon materials were examined by scanning electron microscopy,Brunauer-Emmett-Teller(BET)analysis,X-ray diffraction and Fourier-transform infrared *** surface topography,pore structure,active material,and functional groups of AC,HNO_(3)/AC,and Fe-Mn/AC were systematically *** following results were *** surface of HNO_(3)AC has more ditches and air voids;the micropores of HNO_(3)AC are deformed and flattened compared to those of *** surface of Fe-Mn/AC exhibits an accumulation ***_(2)O_(4)and FeMn_(2)O_(4)formed more pore *** and HNO_(3)AC have numerous *** higher loading quantity of Fe-Mn results in bigger specific *** active components of Fe-Mn/AC-1,Fe-Mn/AC-2,Fe-Mn/AC-3,and Fe-Mn/AC-4 are MnFe_(2)O_(4),MnO_(0.43)Fe_(2.57)O_(4),Mn_(3)O_(4),and ot-Fe_(2)O_(3)*** surface functional groups of AC and HNO_(3)AC are oxygen-containing functional *** effect of Fe-Mn modifying conditions on functional group species is rare;however,Fe/AC has more oxygen-containing functional *** research findings can aid in the desulfurization and denitrification of the Fe-Mn/AC catalyst.
