Abstract

Cobalt-magnesium and vanadium magnesium oxide catalysts were prepared by aerogel method. The obtained nanocrystalline materials are characterized by uniform distribution of the active component, which is present in a finely dispersed state amorphous to X-rays. The oxides have unique morphology. The size of their nanoparticles does not exceed 10 nm. The aerogel synthesis method was successfully applied for synthesis of two-component CoOx·MgO and VOx·MgO catalysts active in CO oxidation and propane oxidative dehydrogenation, respectively.
