负载型铂基催化剂在肉桂醛选择加氢中的研究进展

Progress in supported Pt-based catalysts for the liquid-phase selective hydrogenation of cinnamaldehyde

肉桂醛作为一种典型的α,β-不饱和醛,其选择加氢常被用作模型反应来研究催化剂的构效关系.然而,如何获得兼具高活性及高选择性的催化剂具有很大的挑战.铂基催化剂由于具有较高的活性常被用作肉桂醛选择加氢的催化剂,但是,传统方法制备的负载型单金属铂基催化剂,无论是对C=C双键加氢还是C=O双键选择性均不高.近年来,研究人员从电子效应、协同效应以及空间效应等出发,设计合成了一系列高性能负载型铂基催化剂用于肉桂醛的选择加氢.本文将对近3年负载型铂基催化剂在肉桂醛选择加氢中的进展进行归纳和总结,并对催化剂的构效关系进行分析和梳理,希望为进一步合理设计高催化性能的铂基催化剂提供一些借鉴.

The selective hydrogenation of cinnamaldehyde is an important model reaction for investigating the relationship between catalyst structures and regioselectivity.In recent years,researchers have designed and synthesized a series of better-performing,supported Pt-based catalysts for the selective hydrogenation of cinnamaldehyde,based on electronic,synergistic,and geometric effects to improve the selectivity.In this mini-review,we aim to summarize the recent progress in different supported Pt-based catalysts for the selective hydrogenation of cinnamaldehyde and discuss the performance of these supported catalysts to provide ideas for the design of novel better-performing Pt-based catalysts.
