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.
摘要
将 HAuCl(4) 和溶解在离子液体（IL）1-丁基-3-甲基咪唑氯化物[Bmim]Cl 中的纤维素的混合物注入到水性 NaBH4 中，会导致胶体金纳米颗粒/纤维素杂化沉淀物的形成。该过程是一种非常简单和通用的制备（贵金属）/纤维素杂化物的方法的模型示例，可应用于传感、无菌过滤或作为生物材料。
