| Abstract (English): |
5−Hydroxymethylfurfural (HMF), a key biomass-derived platform molecule, can be selectively oxidized to 2,5−diformylfuran (DFF), an important intermediate for bio-based polymers, fine chemicals, and functional materials. Compared to the full oxidation of HMF to 2,5−furandicarboxylic acid (FDCA), the selective formation of DFF requires precise oxidation of the hydroxymethyl group while suppressing overoxidation of the aldehyde group, posing significant challenges in catalyst design and reaction control. This review provides a comprehensive overview of recent progress in the thermal catalytic oxidation of HMF to DFF, with emphasis on the mechanistic pathways, including oxygen source selection, solvent effects, reactive oxygen species generation, and their interplay with active sites. Advances in noble metal catalysts, transition metal oxides, and carbon-based materials are discussed in terms of structural modulation, structure–activity relationships, and catalytic performance. The advantages and limitations of different catalytic systems are critically compared. Finally, key challenges such as selectivity tuning, catalyst stability, mechanistic elucidation, and the development of green, scalable processes are outlined to guide future research on efficient thermal catalytic systems for DFF production [ABSTRACT FROM AUTHOR] |
| Abstract (Chinese): |
5−羟甲基糠醛 (HMF) 作为典型的生物质平台化合物, 其定向氧化产物 2,5−二甲酰基呋喃 (DFF) 在生物基高分子、精细化工及功能材料领域具有重要的应用价值。相较于 HMF 完全氧化生 成呋喃二甲酸 (FDCA) 的路径, DFF 的合成需在选择性氧化羟甲基的同时抑制醛基过度氧化, 反应路 径更为复杂, 对催化剂的活性与选择性调控的要求更高。系统综述了 HMF 热催化氧化制备 DFF 的研 究进展, 重点解析了反应中涉及的多种氧化路径机制, 讨论了氧源种类、溶剂环境、活性氧物种及其与 催化剂活性位点的协同作用。根据催化剂体系的构成与作用机制, 归纳了贵金属催化剂、非贵金属氧 化物催化剂以及碳基催化剂在结构调控、构效关系及性能优化方面的最新进展, 比较了其在 DFF 选择 性转化中的优势与不足。同时, 还指出当前热催化体系在反应选择性控制、催化剂稳定性、机理解析及 绿色工艺构建等方面面临的主要挑战, 并为后续高效热催化剂的设计与应用提供了理论借鉴与研究 基础。 [ABSTRACT FROM AUTHOR] |
