A novel, one-pot method was developed to synthesize gold nanoparticle composite from cellulose (CEL), wool keratin (KER) and chloroauric acid. Two ionic liquids, butylmethylimmidazolium chloride and ethylmethylimmidazolium bis(trifluoromethylsulfonyl)imide were used to dissolve CEL, KER and HAuCl₄. X-ray diffraction and X-ray photoelectron results show that Au³⁺ was completely reduced to Au⁰NPs with size of (5.5 ± 1) nm directly in the composite with NaBH₄. Spectroscopy and imaging results indicate that CEL and KER remained chemically intact and were homogeneously distributed in the composites with Au⁰NPs. Encapsulating Au⁰NPs into [CEL+KER] …
