Circumventing the activity-selectivity trade-off: Pt-Fe-Pt active sites for selective heterogeneous hydrogenation of crotonaldehyde

Abstract

In heterogeneous hydrogenation catalytic reactions, it is challenging to only hydrogenate the target functional group while preserving all other unsaturated bonds. In this issue of Chem, Shen and coworkers reported a Pt-Fe-Pt heterotrimer with densely populated and precisely arranged Pt atoms, which achieved an increased reaction rate and preferential hydrogenation of the C═O bond in crotonaldehyde catalytic properties.
