Summary: In this study, a fraction of structural Mn cations in cryptomelane oxide K-OMS2 were replaced by different cationic dopants, resulting in the weakening of the Mn-O bond and the production of oxygen vacancy defects. The most active catalyst was found to be the ruthenium doped cryptomelane oxide, which exhibited a higher reducibility and a more weakened Mn-O bond force constant value. All the doping processes enhanced the alcohol conversion and showed a high selectivity towards the aldehyde.
