Abstract(s)
A method based on the deconvolution of TPD spectra is proposed for the characterization of surface oxygen
groups, which can act as the active sites on carbon catalysts. The method, which was previously used to
characterize activated carbons oxidized in the gas phase, has been extended and applied to other materials,
carbons oxidized in the liquid phase. It is shown that this method fits quite well the TPD experimental data
of the original activated carbon as well as the gas-phase and liquid-phase oxidized materials and is suitable
to estimate the amounts of each type of oxygen surface groups.
