Environmentally friendly microwave ionic liquids synthesis of hybrids from cellulose and AgX (X = Cl,Br)

The purpose of this article was to explore an environmentally friendly strategy to synthesis of biomass-based hybrids. Herein, microwave-assisted ionic liquids method was applied to fabricate the hybrids from cellulose and AgX (X = Cl, Br) using cellulose and AgNO₃. The ionic liquids act simultaneously as a solvent, a microwave absorber, and a reactant. Ionic liquids provided Cl⁻ or Br⁻ to the synthesis of AgCl or AgBr crystals; thus no additional reactant is needed. The products are characterized by X-ray powder diffraction (XRD), Fourier transform infrared spectrometry (FTIR), scanning electron microscopy (SEM), thermogravimetric analysis (TGA), and differential thermal analysis (DTA). The cellulose–Ag/AgCl hybrid and cellulose–Ag/AgBr hybrid were also obtained by using cellulose–AgCl and cellulose–AgBr hybrids as precursors. This environmentally friendly microwave-assisted ionic liquids method is beneficial to the hybrids with high dispersion.
