Au, Pd (mono and bimetallic) catalysts supported on graphite using the immobilisation method - Synthesis and catalytic testing for liquid phase oxidation of glycerol

The selective oxidation of glycerol was performed using mono and bimetallic catalysts based on An and Pd and supported on graphite. Moreover, the preparation of bimetallic systems (Au-Pd) was investigated by using different procedures based on sol immobilisation method. The results showed that the use of a bimetallic system significantly improved the activity with respect to the monometallic system; whereas, the selectivity to glyceric acid showed to be dependent upon the reaction temperature and the preparation method used.
