In the face of the current energy and environmental problems, the full use of biomass resources instead of fossil energy to produce a series of high-value chemicals has great application prospects. 5-hydroxymethylfurfural (HMF), which can be synthesized from lignocellulose as a raw material, is an important biological platform molecule. Its preparation and the catalytic oxidation of subsequent products have important research significance and practical value. In the actual production process, porous organic polymer (POP) catalysts are highly suitable for biomass catalytic conversion due to their high efficiency, low cost, good designability, and environmentally friendly features. Here, we briefly describe the application of various types of POPs (including COFs, PAFs, HCPs, and CMPs) in the preparation and catalytic conversion of HMF from lignocellulosic biomass and analyze the influence of the structural properties of catalysts on the catalytic performance. Finally, we summarize some challenges that POPs catalysts face in biomass catalytic conversion and prospect the important research directions in the future. This review provides valuable references for the efficient conversion of biomass resources into high-value chemicals in practical applications.
面对当前的能源和环境问题，充分利用生物质资源替代化石能源来生产一系列高价值化学品具有广阔的应用前景。5-羟甲基糠醛（HMF）可由木质纤维素作为原料合成，是一种重要的生物平台分子。其制备及后续产物的催化氧化具有重要的研究意义和实用价值。在实际生产过程中，多孔有机聚合物（POP）催化剂因其高效、低成本、良好的可设计性和环境友好等特点，非常适合生物质催化转化。在此，我们简要介绍各类POPs（包括COFs、PAFs、HCPs和CMPs）在木质纤维素生物质制备HMF及催化转化中的应用，并分析催化剂结构性质对催化性能的影响。最后，我们总结了POPs催化剂在生物质催化转化中面临的一些挑战，并展望了未来重要的研究方向。本综述为生物质资源在实际应用中高效转化为高价值化学品提供了有价值的参考。
