Advances in non-noble metal catalysts for the selective oxidation of 5-hydroxymethylfurfural

摘要:

5-羟甲基糠醛（HMF）作为一种连接生物质资源和精细化学品工业的多功能平台化合物，因含有醛基、羟甲基而具有非常活泼的化学性质。HMF催化选择氧化在生物质转化过程中具有十分重要的意义，近年来受到研究者们的广泛关注。其氧化产物如2,5-呋喃二甲醛（DFF）和2,5-呋喃二甲酸（FDCA）都是具有高附加值的精细化学品，可用于抗菌剂、医药中间体、合成聚酯等方面。非贵金属催化剂因具备低成本、资源丰富以及环境友好的优势，用于HMF选择氧化的相关报道已逐渐增多。阐述了HMF选择氧化的催化反应机理，着重从非贵金属催化剂的角度出发，对近年来HMF的不同催化氧化体系进行了总结和归纳。最后，展望了HMF选择氧化的研究前景，为构建绿色、高效的催化体系提供思路和参考。

Abstract:

As a versatile platform compound connecting biomass resources and chemical industry, 5-hydroxymethylfurfural (HMF) has very active chemical properties due to its aldehyde group and hydroxymethyl group. The catalytic oxidation process based on HMF is very important for biomass conversion which has attracted the attention of many researchers in recent years. The oxidation products of HMF, such as 2, 5-diformylfuran (DFF) and 2, 5-furandicarboxylic acid (FDCA), are fine chemicals with high value-added which can be used in antibacterial agents, pharmaceutical intermediates, synthetic polyester and other aspects. On account of low cost, abundant resources and environmental friendliness, non-noble metal catalysts have been gradually reported in the selective oxidation of HMF. The mechanism of HMF selective oxidation is described and different HMF catalytic oxidation systems in recent years are summarized based on non-noble metal catalysts. Finally, the research prospect of HMF selective oxidation is prospected which provides the basis and ideas for the construction of green and efficient catalytic system.
