Synthesis of nanoporous carbon with pre-graphitic domains

The effect of precursor structure on porous carbons produced by iron-catalyzed graphitization of biomass

“…At 0 hr hold time, the XRD pattern (Fig 7a) shows that Fe 3 C has fully formed, but the graphite peak is extremely broad and shifted to a low 2θ, suggesting that only turbostratic carbon is present in the system. 28 The very broad, merged Fe 3 C peaks suggest that the Fe 3 C particle size is very small at 0 hr hold time and grows over the course of the 2 hours hold, indicated by the Fe 3 C peaks becoming sharper. This is confirmed by SAXS data (Fig.…”

“…4c) shows a more significant contribution to the scattering from very small features in the sample, suggesting the presence of more micropores, possibly linked to the significant amounts of turbostratic carbon in this sample (as indicated by XRD data). 28 Furthermore, upon acid washing, the size distribution histogram changes shape significantly ( Fig. S3h), with a drop in the relative volume fraction across many length-scales.…”

High energy density capacitor using coal tar pitch derived nanoporous carbon/MnO2 electrodes in aqueous electrolytes

“…KOH activation also leads to carbon with a very low bulk density, an important parameter for determining the volumetric capacitance of the carbon. Alternatively, physical activation using steam or CO 2 avoids contamination since it is a simple burn-off process [24,25]. However, it is usually ineffective at creating porosity in pitch derived carbons [18].…”

Role of Additives in Formation of Solid–Electrolyte Interfaces on Carbon Electrodes and their Effect on High‐Voltage Stability

“…0.5 nm. [14,15] Many studies have focused on improving the electrode/electrolyte stability of lithium-ion batteries. 0.8 nm.…”

“…[11] A lack of heteroatoms also enables this carbon to be partially graphitized at high temperatures, > 2000 8C, which is unusual for non-graphitizing carbons. [14,15] Many studies have focused on improving the electrode/electrolyte stability of lithium-ion batteries. One of the ways to stabilize the electrode/electrolyte interface is to use solvents other than alkyl carbonates.…”
