Resumo

The aim of this study was to use DSC and X-ray diffraction measurements to determine the pore size and pore wall thickness of highly ordered SBA-15 materials. the DSC curves showed two endothermic events during the heating cycle. These events were due to the presence of water inside and outside of mesopores. the results of pore radius, wall thickness and pore volume measurements were in good agreement with the results obtained by nitrogen adsorption measurement, XRD and transmission electron microscopy.
