Synthesis and applications of molybdenum (IV) oxide

Abstract

Molybdenum dioxide (MoO 2) is a transition metal oxide with unusual metal-like electrical conductivity and high catalytic activity toward reforming hydrocarbons. This review covers the synthesis techniques used to fabricate MoO 2 in a variety of morphologies and particle sizes. Processing from molybdenum ore and reduction from MoO 3 are also covered, with emphasis on reduction mechanisms and kinetic considerations. Discussions of various solution-based and gas phase synthesis techniques shed light on strategies to achieve various unique morphologies, which leads into a brief discussion of nanoscale MoO 2. Nanoscale MoO 2 is of interest for important technological applications including catalysts for partial oxidation of hydrocarbons, solid oxide fuel cell anodes, and high-capacity reversible lithium ion battery anodes. © 2011 Springer Science+Business Media, LLC.
