Special Issue Information

Dear Colleagues,

Current material advances have entrenched polymeric carbon nanomaterials as the rapidly emerging interface across a diversity of functional materials for flexible electronics, sensors, biotechnology, catalysis, energy storage, and conversion. Rational design of polymeric carbon nanostructures (PCNs) enriched with well-orderedgeometry as well as superiorelectrical, optical, and mechanical properties. The amalgamation of polymeric carbon nanostructures with metals, inorganic semiconductors etc. have been endowed with multiple functionalities.

This Special Issue on “Polymeric Carbon Nanomaterials in Energy and Environmental Remediation” will address advances in experimental aspects of the synthesis, processing, characterization and possible application in catalysis, water splitting, energy conversion and storage devices, environmental remedy etc.

This Special Issue, entitled "Women in Polymer Science and Technology: Polymeric Carbon Nanomaterials in Energy and Environmental Remediation”, invites submissions by women and men working together with the aim of fighting the inequalities faced by women in the scientific field and also recognizing women’s abilities and their contributions to science. Topics of interest for publication in this Special Issue include but are not limited to:

  • Semiconducting polymers
  • 2D polymeric materials (Graphitic carbon nitrides/ Covalent organic frameworks/ metal organic frameworks)
  • Nanocomposites
  • Photocatalysis
  • Novel approaches for the fabrication of polymeric carbon nanomaterials
  • Polymeric carbon in Photovoltaic Conversion
  • Polymeric carbon in Energy Storage Devices (Batteries & Supercapacitors)
  • Polymeric carbon nanostructures for pollutant degradation
  • Polymeric carbon nanostructures in photo and electrochemical CO2 reduction

This Focus Issue collects original research, comprehensive review papers, as well as communications from research groups with diverse backgrounds in polymeric carbon nanomaterials to discuss all aspects of energy conversion and storage devices, environmental remediation applications.

Hydrogen peroxide (H2O2) is a key chemical for many industrial applications, yet it is primarily produced by the energy-intensive anthraquinone process. As part of the Power-to-X scenario of electrosynthesis, the controlled oxygen reduction reaction (ORR) can enable the decentralized and renewable production of H2O2. We have previously demonstrated that self-supported electrocatalytic materials derived from polyaniline by chemical oxidative polymerization have shown promising activity for the reduction of H2O to H2 in alkaline media. Herein, we interrogate whether such materials could also catalyze the electro-conversion of O2-to-H2O2 in an alkaline medium by means of a selective two-electron pathway of ORR. To probe such a hypothesis, nine sets of polyaniline-based materials were synthesized by controlling the polymerization of aniline in the presence or not of nickel (+II) and cobalt (+II), which was followed by thermal treatment under air and inert gas. The selectivity and faradaic efficiency were evaluated by complementary electroanalytical methods of rotating ring-disk electrode (RRDE) and electrolysis combined with spectrophotometry. It was found that the presence of cobalt species inhibits the performance. The selectivity towards H2O2 was 65–80% for polyaniline and nickel-modified polyaniline. The production rate was 974 ± 83, 1057 ± 64 and 1042 ± 74 µmolH2O2 h−1 for calcined polyaniline, calcined nickel-modified polyaniline and Vulcan XC 72R (state-of-the-art electrocatalyst), respectively, which corresponds to 487 ± 42, 529 ± 32 and 521 ± 37 mol kg−1cat h−1 (122 ± 10, 132 ± 8 and 130 ± 9 mol kg−1cat cm−2) for faradaic efficiencies of 58–78%.
