Porous Anodic Aluminum Oxide as an Efficient Support for Ruthenium-Catalyzed Aerobic Oxidation of Alcohols and Amines

초록

The oxidation reactions of alcohols and amines to their respective aldehydes/ketones and nitriles are important reactions in the laboratory and industry. A highly robust and activated ruthenium-supported anodic aluminum oxide (Ru@AAO) has been synthesized through the sonochemical method. The sonochemical technique allowed a short synthesis time and uniform distribution of Ru on the AAO surface as confirmed by the scanning electron microscopy, transmission electron microscopy, X-ray diffraction analysis, and BET surface-area analysis. The synthesized catalyst was employed for the oxidation of alcohols and amines in the presence of atmospheric air at a relatively lower temperature. The synthesized catalyst showed excellent conversions of both alcohols and amines with high selectivities toward their respective aldehydes/ketones and nitriles. The function of the AAO support in Ru@AAO catalytic activity has also been elaborated in the present investigation.
