    • Treatment of the MCM-41 sample at high temperature brings about the change in the crystallinity of the surface as well as in the structure of the bulk lattice. This process relates to both the number and nature of silanol groups and also local atomic ordering. It is expected that surface ordering provides a stable structure, resulting in the decrease in the number of surface OH groups.

    • The deconvolution of the IR bands observed in both stretching vibrational regions of OH and CO was performed on the basis of the overall knowledge on the location of the OH and CO stretching vibrational bands of the respective samples.
