Special Issue Information

Dear Colleagues,

The electrochemical description, characterization and application of planar carbon-based electrodes, e.g., glassy carbon, edge plane or basal plane electrodes or boron-doped diamond electrodes, are well established in the literature. However, the increase in surface area, for example, the incorporation of roughness or simply the preparation of three-dimensional electrodes through the presence of pores, nanostructures, or mesostructures, modifies the diffusion events and consequently introduces complexity in the reaction rate linked to pore type, pore size distribution, number and different active sites. Understanding of the impact of porosity on the yield, conversion, faradaic efficiency and selectivity of an electrochemical reaction deserves a more rational study for porous carbon-based electrodes. Moreover, knowledge of limited mass transport is crucial to be considered in porous electrodes, thereby modulating electrochemical mechanisms. Hence, the scope of this Special Issue includes, but is not limited to:

  • Novel preparation of gas diffusion electrodes;
  • Scalability of gas diffusion electrodes;
  • Electrosynthesis inside the porosity;
  • Energy transformation and energy storage;
  • Wastewater treatments;
  • Electrochemical sensing and biosensing;
  • Free metal catalyst porous carbon-based electrodes. 

The Guest Editors are pleased to invite you to contribute original experimental and theoretical full or critical minireviews, reflection articles or research manuscripts to the forthcoming Special Issue, “Porous carbon-based electrodes”, of C. Reflections and critical (mini)reviews on recent progress and trends in porous carbon-based electrode preparation and their applications are welcome, and will help academics and researchers in fields such as electrochemistry, materials science and chemical engineering, among others.

In this work, a manganese oxide electrode, containing carbon nanofiber composites (MnO2/CNF), has been made through electrospinning, oxidization, and partial carbonization high-temperature treatment. Scanning electron microscopy (SEM) was used to observe the morphology of the nanofiber and analyze the composition of the fiber. The fiber size range and element distribution were determined. The oxide nanoparticles were modeled as electrorheological suspensions in the polyacrylonitrile polymer solution during electrospinning. The dielectrophoretic behavior of the particles subjected to non-uniform electric fields were analyzed and the motion of the oxide particles under the actions from fluctuating electric fields was investigated to explain the sporadic distribution of nanoparticles within the composite nanofibers. A photoactive anode was made from the composite nanofiber and the decomposition of spilled oil was performed under sunlight illumination. It was observed that the manganese oxide containing carbon nanofiber composite electrode can generate electricity and clean the spilled oil under sunlight. Both energy conversion and environment cleaning concepts were demonstrated. Full article

Among typical energy storage devices, supercapacitors play a predominant role in industry and our life owing to their rapid charge/discharge rate, superior lifespan, high power density, low cost, and outstanding safety. However, their low energy density has severely hindered their further development. For active electrode materials, graphene-based mesoporous nanosheets (GMNs) can combine the advantages from graphene and mesoporous materials, which can be applied to significantly enhance the energy density of supercapacitors. Here, we review the recent advances in GMNs for supercapacitors, focusing on in-plane mesoporous graphene and sandwich-like graphene-based heterostructures. Firstly, the synthesis of in-plane mesoporous graphene with ordered and disordered mesopores for supercapacitors is introduced. Secondly, sandwich-like graphene-based heterostructures are classified into mesoporous carbon/graphene, mesoporous heteroatom-doped carbon/graphene, mesoporous conducting polymer/graphene, and mesoporous metal oxide/graphene, and their applications in supercapacitors are discussed in detail. Finally, the challenges and opportunities of GMNs for high-performance supercapacitors are proposed. Full article
