Preparation of Hybrid Nanocomposites Based on Nanoscale Cellulose and Magnetic Nanoparticles with Photocatalytic Properties

摘要

A low-temperature solution-based method for the production of hybrid organic-inorganic nano-composite films based on nanoscale cellulose and magnetic iron oxide nanoparticles (CNC/Fe_3O_4) was developed. The obtained nanomaterials were investigated by scanning electron microscopy (SEM), dynamic light scattering (DLS), energy dispersive spectroscopy analysis (EDS) and X-ray diffraction analysis (XRD), thermogravimetric analysis (TGA), and FT-IR spectroscopy. The formation of CNC/Fe_3O_4 nanocomposite was confirmed by the XRD analysis. According to SEM images, Fe_3O_4 nanoparticles are uniformly distributed on the surface of nanocellulose. The obtained nanocomposite material exhibits photocatalytic activity under visible light and U Ⅴ irradiation in the rhodamine B degradation reaction. Thus, the developed biocom-patible and environmentally friendly hybrid nanomaterials have great prospects of practical application in the field of biomedicine and photocatalysis.
