Abstract
Researchers synthesized four distinct structural types of Mo₃VO_x catalyst by a hydrothermal method as a single phase.  They characterized them structurally and tested them for oxidative dehydrogenation of ethane.
The catalysts have a common structural feature in that the materials are a layer-type structure and are constructed with pentagonal {Mo₆O₂₁} units. The arrangement of the pentagonal units can form heptagonal channels to create various structural features. The orthorhombic Mo₃VO_x catalyst has microporosity due to the open heptagonal channels adsorbing nitrogen molecules and showed the highest activity for the reaction among four distinct catalysts.
