In: Rsc Advances, 4 (41), pp. 21553-21558. [Article]

Abstract

Novel materials based on sustainable materials with high absorption capacity are still rare for the separation of organic liquids or oil spills and water. In this report, ultra-light nanocomposite aerogels consisting of sustainable bacterial cellulose (BC) and graphene oxide (GO) were constructed after an eco-friendly freeze-drying process for the first time. Due to the hydrophilic properties of both materials and the highly porous structure, BC/GO aerogels could highly absorb not only organic liquids, such as cyclohexane and DMF, but also water. Specific absorption for organic liquids was achieved after the reduction of GO using H-2 gas, which led to nanocomposite aerogels of BC and reduced GO. They could specifically absorb 135-150 g organic liquids per g of their own weight, even with a high content of 80 BC in the nanocomposite aerogel.
