“…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.…”
