Abstract
The effect of vanadium present in nanocrystalline mesoporous VO x-MgO aerogels on the destructive sorption of difluorodichloromethane was studied using tapered element oscillating microbalance (TEOM), synchronous thermal analyzer (STA) and mass-spectrometric analysis of the gas phase. Vanadium incorporation in the aerogels was found to increase the MgO conversion to MgF2 and shorten the induction period of the solid-state reaction. The mechanisms of the CF2Cl2 reaction with pure and vanadium-modified nanocrystalline MgO aerogels based on the obtained data are analyzed. The obtained results suggest that the formation of nuclei related to the surface active sites is the rate-determining stage of the solid-state reaction.
