Synthesis of Orthorhombic Mo-V-Sb Oxide Species by Assembly of Pentagonal Mo6O21 Polyoxometalate Building Blocks


  • Supported in part by “Grant for Research” of The Japan Petroleum Institute and “Nanotechnology Support Project” of the Ministry of Education, Culture, Sports, Science and Technology (MEXT) (Japan), and CREST-JST. The synchrotron radiation experiments were performed at the BL02B1 in the SPring-8 with the approval of the Japan Synchrotron Radiation Research Institute (JASRI; Proposal No. 2007A1497). D.A.B and T.V. thank the State of South Carolina and the Vice President of Research & Health Sciences at the University of South Carolina for generous support.


Mix and match: The pentagonal [Mo6O21]n polyoxomolybdate building block assembles with other sources of Mo, V, and Sb ions to form an orthorhombic Mo-V-Sb oxide. The first single-crystal X-ray analysis of an orthorhombic Mo–V-based oxide, a promising catalyst for light alkane selective oxidation known as the “M1 phase”, revealed the structure of the compound.
