Oxidative dehydrogenation of isopropyl alcohol on mixed tin and antimony oxide catalysts

From studies of the oxidative dehydrogenation of isopropyl alcohol on various compositions of mixed tin and antimony oxide catalysts, it is concluded that this mixed oxide system predominantly functions as Sb2O4 which is formed as a two-dimensional layer on the tin oxide matrix. At low concentrations of antimony and at low temperatures the solid solution-antimony oxide interface may be responsible for the observed activity. The participation of lattice oxygen in the process is also deduced. © 1984.
