Multiphase Flow Systems for Selective Aerobic Oxidation of Alcohols Catalyzed by Bimetallic Nanoclusters

Abstract

Abstract Au–Pt and Au–Pd bimetallic nanoclusters that catalyzed the aerobic oxidation of alcohols during a once-through pass through gas–liquid–liquid–solid flow systems were developed. Alcohols were converted to aldehydes and ketones in benzotrifluoride (BTF)/water media by Au–Pt catalyst or to the corresponding methyl esters in methanol/water media by Au–Pd catalyst. The flow systems were superior to the batch systems in terms of both yield and selectivity.
