摘要：

Sb-Nb-V composite oxides were investigated for the ammoxidation of propane to acrylonitrile. The catalytic activity of SbNbO4 being isostructural to the alpha-Sb2O4 was very low. However, SbNbO4 containing vanadium (V4+) dissolved in the solid solution showed an increased catalytic activity and enhanced selectivity for acrylonitrile. The ammoxidation of propane is supposedly carried out on the cleavage of the [010] plane that is constructed with coordination-unsaturated Nb5+ ions and double-bond oxygen ions combined with Sb5+ ions created by substitution of V4+ ions for Nb5+ ions.
