The Characterization of a Novel Metathesis Catalyst, β-Titanium Oxide-supported Molybdenum Oxide

The results of the X-ray photoelectron spectroscopy of a novel metathesis catalyst, MoOx/β-TiO2, are discussed with reference to its catalytic behavior. It is concluded that the active center for the metathesis reaction of olefin is the molybdenum ion with an oxidation higher than +4 on the average,...

Summary:The results of the X-ray photoelectron spectroscopy of a novel metathesis catalyst, MoOx/β-TiO2, are discussed with reference to its catalytic behavior. It is concluded that the active center for the metathesis reaction of olefin is the molybdenum ion with an oxidation higher than +4 on the average, and that the hydrogen scrambling of olefin during the metathesis is caused by the OH group on the TiO2 surface. During the preparation of this catalyst, the decomposition of titanic acid to TiO2 is found to be accelerated by MoO3; a similar thing can be seen of the reduction of MoO3 to zero-valent molybdenum by TiO2.
