摘要

α-Al2O3 has been modified by the deposition of different amounts of polyacryloni-trile (PAN) via precipitation radical polymerization in an aqueous suspension. Carbonization of the product performed in an inert atmosphere at 350 °C resulted in obtaining of a carbon layer supported on the surface of α-Al2O3. The content of carbon in the composites was determined by temperature-programmed oxidation, whereas textural properties of the synthesized samples were studied by low-temperature sorption of N2 (BET). The carbon/α-Al2O3 composites appeared to be effective adsorbents of methyl ethyl ketone vapour.
