Abstract

Abstract Pd/Ni bimetallic clusters have been successfully prepared for the first time by a polyol reduction method, in which a mixed solution of Pd and Ni salts were reduced at high temperature by ethylene glycol. The bimetallic clusters are proved by TEM, XRD and preliminary EXAFS analysis to have an alloy structure. The bimetallic clusters show much higher catalytic activity for hydrogenation of nitrobenzene to aniline under mild conditions than the monometallic Pd or Ni clusters.
