Special Issue Information

Dear Colleagues,

High-performance supercapacitor devices have been caught great attention to addressing the ever-increasing energy storage concerns. Carbon-based materials are at the forefront to address that concern due to their high-power density, excellent thermal stability, high conductivity, and exceptional stability in both acidic and alkaline conditions. Moreover, abundantly available in nature and low cost are other important factors that made carbon materials have been always within attention among the energy companies and researchers. On the other hand, the depletion of natural combustion-based energy sources due to the growing demands of energy in different sectors such as transportation, industrial, and agricultural may lead to an energy crisis. In this scenario, achieving secure and sustainable energy sources for the next generation is one of the biggest challenges to humankind. Hydrogen generation from the splitting of water and fuel cell technologies are the front-liner alternative and renewable energy sources. Carbon materials are important candidates for enhancing water splitting.

Herein, this special issue covers the design, synthesis, physicochemical characterization, and any electrochemical performances of any carbon materials, their composites, and modifications. Carbon materials include carbon nanotubes, carbon nano/microspheres, carbon nanofibers, graphene, fullerene, etc.). We invite authors to submit their original research work as well as review articles with major focus on carbon-based materials for energy storage and water splitting, carbon dioxide reduction, photo catalysis applications.

In this study, we have evaluated the effect of potassium hydroxide (KOH) on the energy storage performance of metal-free carbon-based materials prepared from molasses. Molasses are a renewable-resource biomass and economical by-product of sugar refinement, used here as a carbon precursor. Two co-doped carbon materials using molasses were synthesized via a time and cost-efficient microwave carbonization process, with ammonium polyphosphate as a phosphorus and nitrogen doping agent. The phosphorus and nitrogen co-doped carbon (PNDC) samples were prepared in the presence and absence of a chemical activating agent (KOH), to study the role of chemical activation on PNDCs. Physical characterizations were performed to gain insight into the composition, pore size and topographical data of each material. Electrochemical characterization via cyclic voltammetry in 1 M sulfuric acid (H2SO4) as well as in 6 M KOH as electrolytes, revealed high current density and specific capacitance for the chemically activated material (PNDC2) compared to one without chemical activation (PNDC1). The capacitance value of 244 F/g in KOH electrolyte was obtained with PNDC2. It is concluded that addition of KOH prior to carbonization increases the surface functionality, which significantly enhances the electrochemical properties of the PNDC material such as current density, stability, and specific capacitance.
