A surface phonon mode at around 961 cm-1, connected with the mesoporous structure was observed. At the annealing temperature of 800 °C, the mesoporous structure of the molecular sieve was found to collapse completely, based on Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) measurements. Further annealing of MCM-41 results in transformation to the cristobalite phase of silica.||Source Title:||Journal of Physics and Chemistry of Solids||URI:||http://scholarbank.nus.edu.sg/handle/10635/98368||ISSN:||00223697||DOI:||10.1016/S0022-3697(99)00010-4|
