Catalytic Behavior of Au Core/Pd Shell Bimetallic Nanoparticles on Silica Prepared by Sonochemical and Sol-Gel Processes

摘要

A unique catalyst, Au core and Pd shell bimetallic naoparticles immobilized on porous silica exhibiting a considerable high activity for the hydrogenation of cyclohexene, was prepared via two steps compsoed of the sonochemical reduction method and the sol-gel process under a low temperature condition.
