Abstract

Injection of a mixture of HAuCl(4) and cellulose dissolved in the ionic liquid (IL) 1-butyl-3-methylimidazolium chloride [Bmim]Cl into aqueous NaBH4 leads to colloidal gold nanoparticle/cellulose hybrid precipitates. This process is a model example for a very simple and generic approach towards (noble) metal/cellulose hybrids, which could find applications in sensing, sterile filtration, or as biomaterials.

A: Structure of [Bmim]Cl. B: XRD pattern of a sample prepared via injecting a solution 20 mg of cellulose and 20 mg of HAuCl4·3H2O in 1 g of [Bmim]Cl into aqueous NaBH4. The pattern from ref. [18] is displayed for comparison. C: magnified (111) and (311) reflections showing the superposition of two Lorentzians for (311). Symbols are experimental data, green lines are individual Lorentzians, and red line is the superposition.
