Facile synthesis of novel MnOx nano-structures and their catalytic performance on CO oxidation†
Abstract
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 MnOx nano-particles have been demonstrated to be catalytically stable and active for CO oxidation.
