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