The presence of humins during the conversion of concentrated fructose presents a major obstacle in the large-scale production of 5-hydroxymethylfurfural (HMF) from fructose. Herein, we reported a boron-doped graphitic carbon nitride sulfonated (BGCN-SOH) as an excellent catalyst for the synthesis of HMF from fructose. The BGCN-SOH catalyst structures were analyzed using various characterization techniques, including X-ray diffraction (XRD), scanning electron microscopy (SEM), thermogravimetric analysis (TGA), energy-dispersive X-ray spectroscopy (EDX), elemental mapping analysis, and Fourier-transform infrared spectroscopy (FT-IR). The BGCN-SOH catalyst was evaluated for the synthesis of HMF from fructose. We investigated the influence of catalyst performance, including solvent reactions, catalyst loading, substrates, and volume of solvent to optimize reaction conditions. As a result, the yield of HMF was obtained at 88 % within 5 h when using 30 mg of catalyst. The study of catalyst activity involved examining reactions that allowed recovery and reuse. The research findings offer a method for producing HMF with exceptional efficiency using solid catalysts.
在浓果糖转化过程中腐殖质的存在是果糖大规模生产5-羟甲基糠醛（HMF）的主要障碍。在此，我们报道了一种硼掺杂的石墨相氮化碳磺化催化剂（BGCN-SOH），它是一种用于从果糖合成HMF的优异催化剂。使用各种表征技术对BGCN-SOH催化剂结构进行了分析，包括X射线衍射（XRD）、扫描电子显微镜（SEM）、热重分析（TGA）、能量色散X射线光谱（EDX）、元素映射分析和傅里叶变换红外光谱（FT-IR）。对BGCN-SOH催化剂用于从果糖合成HMF进行了评估。我们研究了催化剂性能的影响，包括溶剂反应、催化剂负载量、底物和溶剂体积，以优化反应条件。结果，使用30mg催化剂时，5小时内HMF的产率达到88%。对催化剂活性的研究涉及考察可回收和重复使用的反应。研究结果提供了一种使用固体催化剂高效生产HMF的方法。
