Carboxyl functionalized SBA-15 type mesoporous molecular sieves synthesized via co-condensation process were characterized by small-angle X-ray scattering (SAXS). Correlation function and chord length distribution theory were used to analyze the pore structure, interface, and periodic information. The pore structure parameters calculated from chord length distribution theory were compared with the Barrett-Joyner-Halenda (BJH) model cal-culation results, which are based on conventional nitrogen adsorption-desorption tests. The results showed that the samples preserved the structure order of their mesostructures since no significant degradation occurred with an increase in carboxyl group loading, except for the samples with a high carboxyl loading of 50% (molar fraction, versus inorganic silica source). There are no significant deviations in the porod curves of all of the samples. The carboxyl groups may become internally embedded within the framework walls of the mesostructure, as opposed to being externally linked to the pore channels via condensation on surface Si—OH sites. Individual pore size and pore wall thickness distribution data were obtained from the chord length distribution theory calculation without modeling. The pore wall thickness distribution data, which are inaccessible by other method, are very helpful for a further understanding of the mesostructure materials.
