Synthesis Strategies of Porous Carbon for Supercapacitor Applications

Biomass derived porous carbon for CO2 capture

Heteroatom-doped carbon materials (HDCMs) have been widely studied as some of the most prominent material candidates for use in a wide range of applications, such as batteries, supercapacitors (SCs), and the oxygen reduction reaction (ORR) Over the past few years, various metal-free heteroatom-doped carbon composites have been developed via integrating different heteroatoms into carbon with different nanostructures, from single-atom doping (N, P, B, S, etc) to multiple heteroatom doping (N/P/S, N/S/B, etc) For the first time, this review comprehensively analyzes the relevant features of HDCMs used in batteries, SCs, and the ORR, and provides guidance for the design of more efficient materials By controlling the content and types of heteroatom-containing reagents, not only the physical and chemical properties of the material can be adjusted, but also the specific surface area and pore volume can be increased via controlling the morphology, thereby enhancing the electrochemical performance of the material Subsequently, this review summarizes the developments and the history of HDCMs, including synthesis methods, the relationship between doping (doping position and content) and performance, reaction mechanisms, and evaluations of systems In addition, the important role of oxygen doping is raised and discussed, to remind researchers not to ignore the role of oxygen in improving material properties Finally, future developments and challenges relating to key technologies in this thriving field are also discussed in this report

Honeycomb-like Porous Carbon with Nanographitic Domains, Supported on Graphene Layers: Applicability for Lithium/Sodium Storage

Nitrogen-doped porous carbon (NCs) have been synthesized by direct pyrolysis of a mixture containing melamine, iron nitrate and ethylene diamine tetraacetic acid (EDTA). Both the addition of melamine and the carbonization temperature play critical roles in the formation of the unique structure. The results demonstrate that NC-700 shows the best electrochemical performance compared to the other samples. High specific capacitance (275 F g−1 at 0.3 A g−1) is obtained in 6 M KOH, and the capacitance still maintains 202 F g−1 when tested at 10 A g−1 (ca. 73.5% capacitance retention). Moreover, the NC-700 also possesses good cycling stability with only a loss of 2.0% after 10 000 cycles at 10 A g−1. The facile preparation method and good electrochemical performance render NCs a promising candidate for supercapacitor applications.
