Removal of notorious sulfur compounds to produce low-sulfur-content (≤10 ppm) diesel is necessary and vital for modern industry and environmental protection. A new type of inorganic-organic hybrid material has been designed and synthesized confining molybdenum-containing polyoxometalate (POM) clusters within porous aromatic framework-1 (PAF-1) cavities named POM-PAF-1. Deep oxidative desulfurization experiments reveal that POM-PAF-1 possesses excellent reactivity under mild conditions, exemplified by a sulfur removal degree of 98.5% dibenzothiophene within 30 min at 30 °C. The improvement in oxidative desulfurization reactivity from traditional porous POM-based catalysts is owing to uniform POMs and lipophilic and porous PAF-1. The high performance of POM-PAF-1 in terms of excellent reactivity and good stability means it has potential in new heterogeneous catalysis.
去除臭名昭著的含硫化合物以生产低硫含量（≤10 ppm）柴油对于现代工业和环境保护而言是必要且至关重要的。一种新型无机-有机杂化材料已被设计并合成出来，即将含钼多金属氧酸盐（POM）簇限制在名为POM-PAF-1的多孔芳香框架-1（PAF-1）腔内。深度氧化脱硫实验表明，POM-PAF-1在温和条件下具有优异的反应活性，例如在30℃下30分钟内二苯并噻吩的脱硫率达到98.5%。与传统的基于多孔POM的催化剂相比，氧化脱硫反应活性的提高归因于均匀的POM以及亲脂性和多孔性的PAF-1。POM-PAF-1在优异的反应活性和良好的稳定性方面的高性能意味着它在新型多相催化中具有潜力。
