Special Issue Information

Dear Colleagues,

Functional carbon-based materials are crucial components in many applications, such as electrochemical energy storage (e.g., in battery or supercapacitor electrodes), molecular transformations (e.g., as catalyst supports or metal-free catalysts), adsorption-based processes (e.g., in gas or water purification), as sensors, or in engineering, to mention a few. Nanoporous sp2-based carbon materials with high specific surface area and pore volume are of particular interest because they combine the typical advantages of carbon (i.e., high chemical/thermal stability and electrical conductivity) with a large interface area between carbon and the surrounding phases as well as beneficial effects of nano-confinement. Such materials play and will play a key role for a sustainable development of our society in the 21st century.

Various structural features of the high surface area carbons, such as the pore size, pore connectivity, pore geometry, surface chemistry/heteroatom-content, electronic properties, or particle morphology have to be tailored in order to achieve optimum performance in the respective application. These features should be precisely controlled to illuminate the influence of the materials’ characteristics in the respective field of use.

We are welcoming submissions of manuscripts dealing with all aspects of controlled and sustainable synthesis, new characterization techniques, and applications of nanoporous carbon-based materials to this special issue of C-Journal of Carbon Research. Contributions that draw important structure-performance-relationships are particularly appreciated.

We are looking forward to your submissions!

With kind regards,

The protein adsorption plays a very important role in biotechnology, biomolecular engineering and it is one of the main factors determining bio- and hemocompatibility of biomedical materials in medical applications, such as blood purification and wound healing. Here we report adsorption properties of two carbon-based materials, thermally expanded graphite (EGr) and graphene nanoplatelets (GnP), for bovine serum albumin (BSA), the most abundant blood plasma protein. The influence of the surface chemistry of expanded graphite on the mechanism of BSA adsorption was studied by using EGr modified with oxygen or nitrogen functionalities. Having low microporosity and the specific surface area in the range of 5 to 50 m2/g, the expanded graphite exhibits high protein adsorption capacity at high equilibrium concentrations, which makes this material a potential candidate for biomedical applications as a carrier for high molecular weight (HMW) drug delivery or adsorption of HMW metabolites. At low equilibrium concentrations, the effect of specific protein-surface functional groups interaction reveals the differences between the adsorption affinity of different surface modified EGr materials to BSA. The adsorption of BSA on GnP with a specific surface area of 286 m2/g and a developed micro-/mesoporous structure did not follow the same mechanism as seen with EGr materials. At low equilibrium concentration of BSA, GnP exhibits high adsorption efficiency. An important finding is that no release of nanoparticles from expanded graphite adsorbents was observed, which makes them potentially suitable for direct contact with blood and other tissues while very small nanoparticles were noticed in the case of graphene nanoplatelets.

Lithium-sulfur (Li-S) batteries are postulated as next-generation electrochemical energy storage devices due to their increased storage capabilities. However, challenges persist from the polysulfide-shuttle effect at the cathode. Soluble sulfur-based species in the cathode cross over to the lithium anode through the separator leading to fading capacity with cycling. This has spurred continuous effort by the scientific community to develop novel cathodes where sulfur species can affix better. A conductive nanostructured graphene network is a suitable candidate that can serve as a scaffold for holding sulfur nanoparticles. Here, a one-pot synthesis of chemically reduced graphene oxide networks prepared from easily accessible graphene oxide is demonstrated. The solution-based method simply allows for impregnation of the graphene oxide network with sulfur nanoparticles through a careful manipulation of pH of the chemical environment. Two routes were chosen for the precipitation of such sulfur nanoparticles: firstly, the dissolution of sulfur in sodium hydroxide into polysulfides followed by acidification and secondly, the acidification of sodium thiosulfate from alkaline media into sulfur nanoparticles. Both graphene oxide materials from the two routes were treated with sodium borohydride to achieve conductive graphene. The second route, with the sulfur nanoparticles derived from the acidification of sodium thiosulfate with chemically reduced graphene oxide, demonstrated favorable electrochemical behavior, showing promise as electrode material for Li-S batteries.
