Mn4+ is known for its high oxidation activity but easily reduces to lower states during thermal treatment, decreasing catalytic activity. To achieve both highly dispersed and higher oxidation state Mn on the support, Mn was incorporated into the B-site of perovskite-type oxide, NaTaO3 (NTO), containing high-valence Ta5+, via hydrothermal synthesis. XAFS analysis revealed that addition of AcO- ions with KMnO4 for the hydrothernal synthesis precursors were effective way to introduce Mn into NTO structure and show the high catalytic activity of 1-phenylethanol oxidation reaction.
