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

Abstract

A low-temperature solution-based method for the production of hybrid organic-inorganic nanocomposite films based on nanoscale cellulose and magnetic iron oxide nanoparticles (CNC/Fe3O4) 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/Fe3O4 nanocomposite was confirmed by the XRD analysis. According to SEM images, Fe3O4 nanoparticles are uniformly distributed on the surface of nanocellulose. The obtained nanocomposite material exhibits photocatalytic activity under visible light and UV irradiation in the rhodamine B degradation reaction. Thus, the developed biocompatible and environmentally friendly hybrid nanomaterials have great prospects of practical application in the field of biomedicine and photocatalysis.
