Abstract

The preparation of reusable and eco-friendly materials from renewable biomass resources such as cellulose is an inevitable choice for the sustainable development. In this paper, Ag/Fe3O4/cellulose nanocrystals (CNC) nanocomposite was prepared and investigated its application in methylene blue (MB) removal. In the procedure, CNC was isolated from Vietnamese coconut husk fibers (CCH) biomass via a formic/peroxyformic acid process treatment and hydrochloric acid hydrolysis. The obtained CNC was used as a starting material to prepare Ag/Fe3O4 nanostructure by facile and green hydrothermal method. The nanocomposite was characterized by X-ray powder diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), thermogravimetric analysis (TGA), and magnetic properties via vibrating sample magnetometer (VSM) analysis. The results showed that Ag/Fe3O4 was formed with a particle structure and dispersed on the CNC surface. All samples exhibited magnetic properties and the saturation magnetization (Ms) of Ag/Fe3O4 composite was reduced from 48 to 12 emu/g with adding CNC. Ag/Fe3O4/CNC magnetic nanocomposite demonstrated good adsorption of MB solution and exhibited a fast catalytic reduction of MB after immersion treatment by NaBH4, which showed potential applications in water treatment.
