Abstract
A process is proposed for the synthesis of nanocrystalline VMg(OH) x and VO x · MgO with specific surface areas of up to 1200 and 470 m2/g, respectively. The synthesized VO x · MgO oxides consist of nanocrystals (2′–5 nm), which form platelike agglomerates. As distinct from conventional impregnation of magnesium oxide, the aerogel process for VO x · MgO synthesis ensures a uniform vanadium distribution in MgO.
