Abstract
Polymer-protected Cu/Pd bimetallic colloids with different atomic ratio of Cu to Pd were successfully prepared by refluxing a glycol solution of hydroxide of copper and palladium in the presence of poly(N-vinyl-2-pyrrolidone). The TEM, XRD, AAS and UV-vis spectrum measurements indicate the formation of bimetallic alloy phase in the bimetallic colloids. High catalytic activity and selectivity for the hydration of acrylonitrile to acrylamide was achieved by using the Cu/Pd(Cu/Pd = 2) bimetallic colloid as a catalyst.This publication has 16 references indexed in Scilit:
