Summary: | [Display omitted]
•We employ a self-assembly technique to fabricate macroporous graphene-based aerogels (GAs).•GAs have been fabricated by using carbohydrate as morphology oriented agents.•The carbohydrates can tailor the microstructures and physical properties of GAs.•The effect of different carbohydrates to form GAs was also discussed systemically.•All the aerogel samples showed good supercapacitor performance.
Homogeneously distributed self-assembling hybrid graphene-based aerogels with 3D interconnected pores, employing three types of carbohydrates (glucose, β-cyclodextrin, and chitosan), have been fabricated by a simple hydrothermal route. Using three types of carbohydrates as morphology oriented agents and reductants can effectively tailor the microstructures, physical properties, and electrochemical performances of the products. The effects of different carbohydrates on graphene oxide reduction to form graphene-based aerogels with different microcosmic morphologies and physical properties were also systemically discussed. The electrochemical behaviors of all graphene-based aerogel samples showed remarkably strong and stable performances, which indicated that all the 3D interpenetrating microstructure graphene-based aerogel samples with well-developed porous nanostructures and interconnected conductive networks could provide fast ionic channels for electrochemical energy storage. These results demonstrate that this strategy would offer an easy and effective way to fabricate graphene-based materials. |
