Abstract
The XPS data show the estimation of 4 types of C-bonds in carbon membranes pyrolyzed in various conditions. As the pyrolysis temperature increases, the relative amount of carbon-carbon bonds increases, while carbon-oxygen, and carbon-nitrogen bonds seem to decrease. Additionally, samples that were exposed to methanol have lower amounts of carbon-carbon bonds and increased amounts of carbon-oxygen bonds relative to samples that were not soaked in methanol. This collection of data was used to hypothesize a representative structure that reflects the average composition and bonding of carbons.
