| 中文摘要: |
| 肉桂醛（CAL）作为典型的α,β-不饱和醛，其选择性加氢产物肉桂醇（COL）与氢肉桂醛（HCAL）是医药合成、高端香精香料等领域的关键中间体。然而，由于C=C键的氢化反应在动力学和热力学上均优于C=O键，如何实现C=O键和C=C键选择性加氢，一直是催化领域的核心挑战。本文综述了贵金属催化剂在肉桂醛选择性加氢中的研究进展，重点介绍了优化催化剂活性的电子效应、协同效应、界面效应和几何效应四种策略以及单原子催化剂的应用。同时，探讨了当前贵金属催化剂面临的局限性，并提出了可行的解决方案。 |
| 英文摘要: |
| Cinnamaldehyde (CAL), a representative α,β-unsaturated aldehyde, undergoes selective hydrogenation to yield cinnamyl alcohol (COL) and hydrocinnamaldehyde (HCAL), which are critical intermediates in pharmaceutical synthesis and high-end flavor and fragrance industries. However, achieving selective hydrogenation of the C=O bond while suppressing the thermodynamically and kinetically favored hydrogenation of the C=C bond remains a central challenge in catalysis. This paper reviews the research progress of noble metal catalysts in the selective hydrogenation of cinnamaldehyde, with a focus on introducing four strategies for optimizing catalyst activity: electronic effect, synergistic effect, interface effect and geometric effect, as well as the application of single-atom catalysts. Meanwhile, the limitations currently faced by precious metal catalysts were discussed, and feasible solutions were proposed. |
