Small Angle X-ray Scattering (SAXS) experiment using Synchrotron Radiation as X-ray source was used to determine the average wall thickness of mesoporous silica prepared by condensation of tetraethylorthosilicate (TEOS) using non-ionic alkylpolyethyleneoxide (AEO₉) surfactant as templates. The results agreed with that of high-resolution TEM (HRTEM) measurement.
- Small Angle X-ray Scattering (SAXS),
- mesoporous silica,
- average wall thickness.
