Structure of methanol confined in MCM-41 investigated by large-angle X-ray scattering technique

The present large-angle X-ray scattering (LAXS) investigation on methanol confined in the MCM-41 C14 (diameter of 28 Angstrom) and C10 (21 Angstrom) pores has shown that the structure of methanol consists of the monolayer methanol on the surface and the hydrogen-bonded chains of methanol molecules at the central part of the pores. The methanol structure cannot be three-dimensionally evolved in the pores with decreasing temperature.
