摘要：
In the hydrogenation of phenylacetylene over several (Pt-Ni)/Al2O3 alloys and mechanical mixtures, it was found that Pt enhances the activity without affecting the semi-hydrogenation selectivity of Ni in both the alloys and the mixtures. The alloys are of lower activity, but of slightly higher selectivity than the mixtures. Incorporation of 10% Ce to the (Pt-Ni)/Al2O3 alloys has increased its activity by 60%, but it did not change its selectivity.
