Abstract

The silica modified by boehmite (15% of Al₂O₃ by mass) was produced by sol-gel method without supercritical drying processes. Aerogel SiO₂/Al₂O₃ textural characteristics was studied by low-temperature nitrogen adsorption with annealing samples at the temperature range of 500−900°C. Concentration and the acidic centers force on the aerogels surface were determined by thermal desorption of ammonia. For the first time absorption spectra of ethylene confined in nanopores of SiO₂/Al₂O₃ aerogels was recorded using a Bruker IFS 125 HR FTIR spectrometer in the 5500 – 6300 cm^-1 region. The difference in profiles of adsorbed ethylene was shown.
