Crystalline MoVO based complex oxides as selective oxidation catalysts of propane
TL;DR: In this paper, three single crystalline Mo V O based oxides were synthesized by hydrothermal method and their catalytic performance in the selective oxidation of propane to acrylic acid were compared in order to elucidate the roles of constituent elements and crystal structure in the course of the propane oxidation.

Ammoxidation of propane over Mo-V-Nb-Te mixed oxide catalysts
TL;DR: Mo-V-Nb-Te mixed metal oxides are highly active and selective for the ammoxidation of propane to acrylonitrile as discussed by the authors, and the efficiency of the catalyst is higher than that of V-Sb and Bi-Mo mixed metal oxide catalysts.
