Fluorinated activated carbon fibers (F-ACFs) were prepared by direct thermal fluorination of pristine activated carbon fibers. By the pyrolysis of F-ACFs at 1073K under nitrogen gas flow, fluorine was subsequently eliminated and the sp 2 -bonded ACF structures were recovered. The micropore widths were 1.1 and 0.8nm, and the isosteric heats of adsorption of nitrogen were 11.3 and 12.8kJ/mol...
Predominant mesopores were added to pitch-based activated carbon fiber (0.7nm of average pore width) by Ca(NO 3 ) 2 -impregnated chemical activation. The influence of the concentration of calcium nitrate solution, reactivation temperature and reactivation time on the mesopore development of ACF were examined. The development of mesopores in the reactivated ACF was evidenced by an explicit...
The X-ray diffraction from CHCl3 molecules adsorbed in slit-shaped micropores of activated carbon fibers were measured at 298 K. The pore effect on structure of molecular assemblies in the graphitic micropores was examined. The peak positions due to the first nearest neighbor CHCl3 in the electron radial distribution function of adsorbed phase agreed with those of bulk liquid, although their peak...
