Tailoring co-doping of cobalt and nitrogen in a fullerene-based carbon composite and its effect on the supercapacitive performance

Abstract

Fullerene-based carbons have attracted great attention in applications of energy storage and conversion due to their unique properties and tunable architectures. However, fullerene's poor long-range conductivity limits their application performance...

Cross-linked copolymer-derived nitrogen-doped hierarchical porous carbon with high-performance lithium storage capability

“…4d depicts the peak fitting results of high-resolution N 1s spectrum, identifying four distinct components of nitrogen, including pyridinic N at 399.1 eV, pyrrolic N at 399.9 eV, graphitic N at 400.8 eV, and oxidized pyridinic-N at 402.3 eV, respectively. [40][41][42] Previous experimental Please do not adjust margins Please do not adjust margins and theoretical investigations indicate that the pyridinic/pyrrolic N decorations on carbons could not only modify their electronic property, but also serve as electrochemically active sites for extra lithium accommodation. 35,40,43,44 The electrochemical properties of N-HCP as a LIBs anode were evaluated by the standard half-cell configuration in a voltage window of 0.01-3.0 V vs. Li/Li + .…”

Recent Advances in Carbon‐Based Electrodes for Energy Storage and Conversion

“…[43] In another work, Jiang and co-workers manipulated fullerene self-assembly with cobalt and nitrogen doping to prepare mesoporous carbon composites. [256] Thanks to the confined state of the cobalt during the calcination, a highly homogeneous distribution of Co,N-doping was obtained within the fullerene-based carbon composites, leading to a significantly as electrodes measured at different scan rates. C) Galvanostatic charge-discharge measurements of the supercapacitor measured at different current densities.…”

Carbon Nanomaterials Based Supercapacitors: Recent Trends

“…It is therefore anticipated that active carbons based on fullerene will have large capacitances when they are developed. By manipulating fullerene self-assembly with a cobalt tetramethoxy phenylporphyrin (CoTMPP) and pyrolysis, mesoporous carbon composites doped with varying Carbon Nanomaterials Based Supercapacitors: Recent Trends DOI: http://dx.doi.org/10.5772/intechopen.106730 concentrations of cobalt (Co) and nitrogen (N) were synthesized by Jiang et al [46]. C 60 crystals encapsulated CoTMPP, which underwent carbonization to become actively-bound Co-N in the carbon structures.…”
