“…Therefore, we expect the effect of the attractive interactions between the polar groups of 1-propanol and the SBA-15 matrix, as well as in the free-volume microstructure of the confined 1-propanol. Similar work was done with confined media by the partial filling of pores with water [3,4] or n-hexadecane [5,6] in irregular matrices. However, these substances crystallize in the bulk state, unlike the amorphous 1-PrOH, which is studied in this work.…”

The free-volume of 1-propanol (1-PrOH) confined in a regular mesoporous SBA-15 matrix was investigated by desorption experiment at room temperature and over a wide temperature range, from 15 K up to 350 K, for four different contents of 1-PrOH in the pores. The gradual desorption of 1-PrOH from the mesopores as well as the free volume temperature dependences have shown that the polar molecules of 1-PrOH located at the inner polar surface of the SBA-15 matrix are more strongly bound to the matrix surface. The subsequent discussion of the annihilation and free-volume characteristics follows.
