Hydroxymethylfurfural (5-HMF) is a vital biomass-derived platform chemical for the production of secondary value-added chemicals. In this work, fructose conversion into 5-HMF over metal–organic framework (MOF) has been considered. Several MOF-based catalysts were synthesized and examined in fructose dehydration into 5-HMF via a microwave-assisted reactor. Each MOF's catalytic performance was evaluated concerning its surface area, pore size, and acid density. The results showed satisfactory fructose conversion levels for all studied MOFs in the range of 60%–99%. As a catalyst, zeolitic imidazolate frameworks (ZIFs) resulted in excellent fructose conversion, but interestingly, higher quantities of side products such as formic and levulinic acids were produced. The higher 5-HMF yields, up to 90%, were obtained over the MIL-101 (MIL, Materials Institute Lavoisier) family, such as MIL-101-SO₃H. This result is ascribed to the fact that functionalized MOF possesses hydrothermal stability, high surface area, and suitable pore sizes.

金属-有机骨架作为果糖转化为 5-羟甲基糠醛的催化剂：催化剂筛选和参数研究

羟甲基糠醛 (5-HMF) 是一种重要的生物质衍生平台化学品，用于生产二次增值化学品。在这项工作中，已经考虑在金属有机框架 (MOF) 上将果糖转化为 5-HMF。合成了几种基于 MOF 的催化剂，并在通过微波辅助反应器将果糖脱水成 5-HMF 的过程中进行了研究。评估了每种 MOF 的催化性能，包括其表面积、孔径和酸密度。结果表明，所有研究的 MOF 的果糖转化率均在 60%–99% 范围内。作为催化剂，沸石咪唑酯骨架 (ZIF) 产生了极好的果糖转化率，但有趣的是，产生了大量的副产物，如甲酸和乙酰丙酸。与 MIL-101 (MIL,₃ H。这一结果归因于功能化 MOF 具有水热稳定性、高表面积和合适的孔径。
