摘要

Abstract

Bimetallic CuPd x nanoparticles synthesized by the wet chemical reduction method were used as the catalysts in the catalytic oxidation of 1

2-propanediol with gaseous oxygen to aliphatic acids. The palladium and copper nanoparticles in the bimetallic CuPd

nanoparticles had an alloying trend. The catalytic activity of the palladium nanoparticles in the bimetallic CuPd

nanoparticles was enhanced by the interaction between the palladium and copper nanoparticles. When the bimetallic CuPd

nanoparticles catalyzed the oxidation of 1

2-propanediol in an alkaline aqueous solution at 100 ℃ for 3 h

lactic

formic

and acetic acids were dominantly produced with the total selectivity of above 99% at the 1

2-propanediol conversion of 85.9%. The simulation of the reaction kinetic equation on the CuPd

catalyst showed that the reaction activation energy was 29.4 kJ·mol

-1

indicating that the bimetallic CuPd

nanoparticles had a high catalytic activity in the oxidation reaction between 1

2-propanediol and gaseous oxygen.
