Special Issue Information

Dear Colleagues,

The Journal of Carbon Research invites you to contribute to the Special Issue, “Graphene Aerogels.” Graphene aerogels are one of the most explored graphene based materials, with several hundred papers published on the topic in the last few years. This popularity is based on the simplicity of the synthetic method used to make graphene aerogels, their outstanding structural electrical adsorption, and other properties that are important for many applications.

This Special Issue invites original research articles, communications, and comprehensive reviews on the synthesis, properties, and applications of graphene aerogels and associated graphene 3-D composites with carbon nanotubes, polymers, proteins, metal and metal-oxide nanoparticles, etc. The scope covers very broad aspects and encompasses: the fundamental concepts of graphene aerogel preparation; the understanding of their unique properties; the engineering of these properties, in combination with other materials, to achieve advanced catalytic, adsorption, electrochemical, magnetic, acoustic, and thermal performances; and the exploration of their broad applications, including in supercapacitors, batteries, heavy metal adsorbents, oil and dye adsorbents, catalysis, drug delivery, etc. The topic will specifically cover recent progress on the development of new synthetic approaches for advanced graphene aerogel composites with different chemical compositions (metals, semiconductors, metal-oxides, polymers, graphene, DNA, enzymes, etc.) and nanoscale dimensions and morphologies (particles, pores, wires, tubes, rods, etc.), and is focused on designing new materials with improved performances and emerging applications.

Carbon aerogels are highly porous materials with a large inner surface area. Due to their high electrical conductivity they are excellent electrode materials in supercapacitors. Their brittleness, however, imposes certain limitations in terms of applicability. In that context, novel carbon aerogels with varying degree of flexibility have been developed. These highly porous, light aerogels are characterized by a high surface area and possess pore structures in the micrometer range, allowing for a reversible deformation of the aerogel network. A high ratio of pore size to particle size was found to be crucial for high flexibility. For dynamic microstructural analysis, compression tests were performed in-situ within a scanning electron microscope allowing us to directly visualize the microstructural flexibility of an aerogel. The flexible carbon aerogels were found to withstand between 15% and 30% of uniaxial compression in a reversible fashion. These findings might stimulate further research and new application fields directed towards flexible supercapacitors and batteries. Full article

The performance of synergetic hybrid aerogel materials of vanadia and graphene as electrode materials in supercapacitors was evaluated. The hybrid materials were synthesized by two methods. In Method I, premade graphene oxide (GO) hydrogel was first chemically reduced by L-ascorbic acid and then soaked in vanadium triisopropoxide solution to obtain V2O5 gel in the pores of the reduced graphene oxide (rGO) hydrogel. The gel was supercritically dried to obtain the hybrid aerogel. In Method II, vanadium triisopropoxide was hydrolyzed from a solution in water with GO particles uniformly dispersed to obtain the hybrid gel. The hybrid aerogel was obtained by supercritical drying of the gel followed by thermal reduction of GO. The electrode materials were prepared by mixing 80 wt % hybrid aerogel with 10 wt % carbon black and 10 wt % polyvinylidene fluoride. The hybrid materials in Method II showed higher capacitance due to better interactions between vanadia and graphene oxide particles and more uniform vanadia particle distribution. Full article
