摘要

在异相氢化催化反应中，只氢化目标官能团而保留所有其他不饱和键是一项挑战。在本期《化学》杂志上，Shen 及其同事报告了一种铂-铁-铂异三聚体，其铂原子密集且排列精确，在巴豆醛催化特性中实现了更高的反应速率和 C═O 键的优先氢化。

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

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.
