Facile synthesis of novel MnOx nano-structures and their catalytic performance on CO oxidation.

A facile hydrothermal method has been employed to fabricate monodisperse Mn₂O₃ nano-flowers and Mn₃O₄ nano-ellipsoids. The possible mechanism of crystal growth was suggested based on time-dependent experiments, and the role that H₂O₂ played in the determination and formation of products Mn₂O₃ and Mn₃O₄ was investigated. These MnO_x nano-particles have been demonstrated to be catalytically stable and active for CO oxidation. [ABSTRACT FROM AUTHOR]
