Bimetallic Co-Pd alloy nanoparticles as magnetically recoverable catalysts for the aerobic oxidation of alcohols in water

Co-Pd bimetallic alloy nanoparticle catalysts were prepared from CoCl2, Pd(OAc)(2) and several capping agents with Li(C2H5)(3)BH. The nanoparticle catalysts were applied to the aerobic oxidation of a variety of alcohols in water to give the corresponding carbonyl products. The catalyst was magnetically recovered and reused for further oxidation. The nanoparticle catalysts were characterized with TEM, ICP, and XPS analyses. (C) 2014 Elsevier Ltd. All rights reserved.
