- Alkene can be completely converted to alkane with high selectivity over Pd/ZSM-5.
- Highly dispersed PdOx species benefits H2 activation.
- PdOx species prefer to be anchored on the H-ZSM-5â²s strong Brönsted acid sites.
- Strength and amount of surface acidity play important role in olefin hydrogenation.
A novel strategy is reported in this study to design a novel bifunctional PdOx/H-ZSM-5 catalyst for selective hydrogenation of olefin. PdOx species (basic oxides) anchored on the strong acidic sites (Brönsted acid sites) of zeolite support could not only generate new acidic sites with moderate acidic strength but also exhibit good capability for H2 activation and dissociation. The conversion of 1-decene is 100% and total selectivity of methyl-nonane is 98.4 ± 0.4% at 350 °C. Our research might provide a valuable approach to design a highly efficient bifunctional catalyst for olefin upgrading.
