Temperature-Controlled Hydrothermal Synthesis of α-MnO Nanorods for Catalytic Oxidation of Cyclohexanone.

This work describes the comparison of the catalytic performances of α-MnO nanorods synthesized by a facile hydrothermal approach at varying temperatures (140-200 °C). The structure and morphology of these nanorods were analyzed by XRD, N-physisorption, NH-TPD, Raman, SEM, HRTEM, and XPS. The prepared α-MnO nanorods also performed exceptionally well in the catalytic oxidation of cyclohexanone to dicarboxylic acids under mild reaction conditions.
