Preparation and catalytic activity of monolayer dispersed Pt/Ni bimetallic catalyst for C=C and C=O hydrogenation

The monolayer dispersed Pt/Ni bimetallic catalyst was prepared through a simple replacement reaction, and its catalytic activity for the hydrogenation of cyclohexene, styrene, acetone, and butyl aldehyde was tested. The Pt/Ni catalyst prepared by the replacement reaction showed much higher activity than Pt/Ni and Pt/Al2O3 catalysts with the same Pt loading prepared by the conventional impregnation method.
