摘要

由于日益严格的环境法规，对硫含量低于15ppm的超清洁燃料的需求日益增加。传统的加氢脱硫方法在去除难降解硫化合物方面存在局限性，需要开发有效的替代方法。超声辅助氧化脱硫（UAODS）因其条件温和、效率高而成为一种很有前途的方法。在此背景下，铋基金属有机框架（Bi-MOF）以其氧化还原性能和结构可调性而被认可，与有序介孔二氧化硅（MS）结合形成一种新型的杂化催化剂（Bi-MOF/MS）。结果本研究制备了一种用于UAODS的分级Bi-MOF/MS催化剂。采用x射线衍射（宽角和小角）、x射线光电子能谱、布鲁诺尔-埃米特-泰勒分析、傅里叶变换红外光谱、透射电镜等手段对催化剂进行了综合表征，证实其结晶度高、多孔结构有序、Bi-MOF/MS相互作用强。系统评价了超声功率、催化剂用量、氧化剂浓度、反应温度、反应时间、萃取溶剂等操作参数对反应效果的影响。在优化条件下，Bi-MOF/MS催化剂的脱硫效率为97.2%。动力学研究和循环实验表明，脱硫性能稳定，5次循环后脱硫效率保持在86.8%。结论有序质谱与层次化Bi-MOF的结合增强了复合材料的结构稳定性、比表面积和协同作用，具有良好的催化活性和可重复使用性。这些发现表明，Bi-MOF/MS混合催化剂是高效和可持续生产超低硫燃料的有希望的候选催化剂。©2025化学工业学会（SCI）。

Enhancing ultrasound-assisted oxidative desulfurization of fuels using hierarchical metal–organic framework and ordered mesoporous silica composite

BACKGROUND

The demand for ultra-clean fuels with sulfur content below 15 ppm has intensified due to increasingly stringent environmental regulations. Traditional hydrodesulfurization methods face limitations in removing refractory sulfur compounds, necessitating the development of efficient alternative approaches. Ultrasound-assisted oxidative desulfurization (UAODS) has emerged as a promising method owing to its mild conditions and high efficiency. In this context, bismuth-based metal–organic frameworks (Bi-MOFs), recognized for their redox properties and structural tunability, were integrated with ordered mesoporous silica (MS) to form a novel hybrid catalyst (Bi-MOF/MS).

RESULTS

This study presents the synthesis and application of a hierarchical Bi-MOF/MS catalyst for UAODS. The catalyst was comprehensively characterized using X-ray diffraction (wide and small-angle), X-ray photoelectron spectroscopy, Brunauer–Emmett–Teller analysis, Fourier transform infrared spectroscopy, and transmission electron microscopy, confirming its high crystallinity, ordered porous structure, and strong Bi-MOF/MS interaction. The effect of operational parameters, including ultrasound power, catalyst dosage, oxidant concentration, reaction temperature, reaction time, and extraction solvents, was systematically evaluated. Under optimized conditions, the Bi-MOF/MS catalyst achieved a sulfur removal efficiency of 97.2%. Kinetic studies and recycling experiments revealed stable performance, with 86.8% desulfurization efficiency retained after five cycles.

CONCLUSION

The integration of ordered MS with hierarchical Bi-MOF enhanced the structural stability, surface area, and synergistic interaction of the composite, leading to excellent catalytic activity and reusability. These findings establish the Bi-MOF/MS hybrid catalyst as a promising candidate for efficient and sustainable production of ultra-low-sulfur fuels. © 2025 Society of Chemical Industry (SCI).
