Special Issue Information

Dear Colleagues,

This Special Issue of Materials invites original research articles, communications and comprehensive reviews on the synthesis, characteristics and applications of doped carbon materials. The scope of this Special Issue covers very broad aspects from synthesis, properties, characterization and applications of a broad range of doped carbon-based materials in different dimensions (0D, 1D, 2D and 3D) and forms including quantum dots (QDs), carbon nanotubes (CNTs), graphene, graphite, porous carbons, nanofibers, carbon 3D hybrids/composites, etc. In particular, the topic will cover progress on their doping by heteroatoms, such as nitrogen, sulphur, boron, oxygen, and others, for developing fascinating intrinsic properties and functionalities (physical and chemical) which are explored in many emerging applications across broad sectors such as advanced catalysis, electro- and photoelectrocatalysis (hydrogen, CO2), energy storage (supercapacitors, batteries), sensing, environmental remediation, biomedical applications and agriculture.

We are looking to receive your valuable contributions and helping to further advancements in this important field.

Prof. Dr. Dusan Losic

In this study, an E-fenton oxidation system based on Co-N co-doped carbon nanotubes (Co-N-CNTs) was designed. The Co-N-CNTs system showed fast degradation efficiency and reusability for the degradation of rhodamine B (RhB). The XRD and SEM results showed that the Co-N co-doped carbon nanotubes with diameters ranging from 40 to 400 nm were successfully prepared. The E-Fenton degradation performance of Co-N-CNTs was investigated via CV, LSV and AC impedance spectroscopy. The yield of H2O2 could reach 80 mg/L/h within 60 min, and the optimal voltage and preparation temperature for H2O2 yield in this system was −0.7 V (vs. SCE) and 800 °C. For the target pollutant of RhB, the fast removal of RhB was obtained via the Co-N-CNTS/E-Fenton system (about 91% RhB degradation occurred during 60 min), and the •OH played a major role in the RhB degradation. When the Fe2+ concentrations increased from 0.3 to 0.4 mM, the RhB degradation efficiency decreased from 91% to about 87%. The valence state of Co in the Co-N-C catalyst drove a Co2+/Co3+ cycle, which ensured the catalyst had good E-Fenton degradation efficiency. This work provides new insight into the mechanism of an E-Fenton system with carbon-based catalysts for the efficient degradation of RhB. Full article
