Аннотация

The developed method for synthesis of binary VOx/MgO aerogels by hydrolysis of the V and Mg alkoxides mixed together followed by gelation and supercritical drying makes it possible to obtain aerogels with exceptionally high surface areas (~ 1200 m2/g) and uniform vanadium distribution. Their dehydration yields nanocrystalline VOx/MgO with nanoparticle size ca. 5 nm. The synthesized nanocrystalline VOx/MgO oxides were used as destructive sorbents for decomposition of halocarbons. The doping of MgO aerogels with a small amount of VOx (1-2%) results in significant acceleration of the reaction with CF 2Cl2 causing deeper MgO transformation to MgF2 and shortening the induction period.
