Nickel based catalyst is of interest in the industrial catalytic processes  and it is always modified by doping a second element to improve its catalytic properties. Understanding the role of dopant is extremely helpful in tailoring the active centers. In this work  Zn could induce a significant improvement of the catalytic performance of NiAl for the hydrogenolysis of glycerol. The Zn doped ZnNiAl catalysts exhibited high activity and the improved selectivity to 1  2-propanediol  it was about 2 times higher than the original ones. The ZnNi alloy formed in ZnNiAl was responsible for the noticeable catalytic performance. They preferred to coordinate with the end hydroxyl group of glycerol  promoted the cleavage of C-O bond in glycerol  and resulted in the dominant formation of 1  2-propanediol. The findings described here will provide a useful knowledge for rational design of nickel-based catalysts  as well as reveal a new reaction model for the hydrogenolysis of glycerol.
