Abstract:In this article， Magnetic CuFe2O4-CNC compositewasprepared via aone-step solvothermal method， using FeCl3， CuCl2， NaAc and CNC as the sources of Fe， Cu， N and carrier， respectively. The magnetic CuFe2O4-cellulose nanocrystals（CuFe2O4-CNC） composites were characterized by inductive coupled plasma emission spectrometer atomic emission spectrometry （ICP-AES）， transmission electron microscopy（TEM）， Fouriertransform infrared spectrometer （FT-IR），X-ray diffraction （XRD）， specific surface areas analyzer （BET）， vibrating sample magnetometer（VSM） and thermogravimetric （TG-DSC）. The results showed that the CuFe2O4-CNC was cubic spinel crystal structure and the composites exhibited a nanosphere structure with about 10 nm. It could be found that the CuFe2O4-CNC composite presented the maximum saturationmagnetization of 171.56 kA/m， respectively. Both of them weresuperparamagnetic materials. The CuFe2O4-CNC composite at 200℃ for 8h had larger specific surface areas and catalytic activity to degrade4-nitrophenol．
