摘要

木质素作为最丰富的天然芳香族化合物，在生产燃料和精细化学品方面具有巨大的潜力，因此成为绿色化学的一个焦点。木质素的高效解聚取决于催化剂的发现，催化剂不仅要高效，而且要稳定和可回收。了解木质素-催化剂解聚的结构-功能关系和机理对于有效实现木质素的价值化至关重要。聚氧甲基丙烯酸酯（POMs）因其结构组成的多样性和设计的灵活性而成为前景广阔的候选材料。在本综述中，我们探讨了在各种木质素转化方法中利用 POMs 的情况，包括氧化催化、还原催化和光催化。通过总结这些方法，我们旨在阐明当前使用 POMs 解聚木质素的趋势和挑战。

The depolymerization of lignin over polyoxometalate catalysis: A review

Lignin, as the most abundant natural aromatic compound, holds immense potential for the production of fuels and fine chemicals, making it a focal point in green chemistry. The efficient depolymerization of lignin hinges on the discovery of catalysts that are not only efficient but also stable and recyclable. Understanding the structure-function relationships and mechanisms governing lignin-catalyst depolymerization is paramount for its effective valorization. Polyoxometalates (POMs) have emerged as promising candidates due to their versatile structural composition and design flexibility. In this review, we explore the utilization of POMs in various methods of lignin transformation, encompassing oxidative catalysis, reduction catalysis, and photocatalysis. By summarizing these approaches, we aim to elucidate the current trends and challenges in the depolymerization of lignin using POMs.
