Abstract
Transformation of C2H4, CO2 and C2H6 absorption spectra under condition of nanoconfinement in SiO2/Al2O3 aerogel is presented for the first time. It is shown that integral intensity of confined C2H4 within 5700-6250 cm-1, CO2 within 4760-5160 cm-1 and C2H6 within 2830-3030 cm-1 are respectively by 13.3, 15, and 18 times higher than in free gas.
