Abstract
By varying the precursor ratios, cobalt doped manganese oxide nanocluster catalysts with different cobalt contents were prepared using the colloidal method. Catalysts were applied to a gas phase benzene oxidation reaction. Among them, the catalyst with a Mn:Co ratio of 90:10 showed the highest conversion. The addition of cobalt changing the valence of manganese was observed by XANES analysis, and that is thought to be the reason for the high activity.
