In this work, a series of organic-inorganic hybrids based on N-alkyl-4-vinylpyridinium bromide ([C_nVP]Br) with different carbon chain lengths and Dawson type heteropolyacid (HMoV) were designed and synthesized. And then the hybrids were loaded on mesoporous carbon aerogel (CA) with a high surface area of 1448.26 m²/g to form supported catalyst ([C_nVP]MoV/CA), which used for extraction-oxidation desulfurization (EODS). Some techniques such as FT-IR, XRD, SEM, EDX, TEM, BET and XPS were used for characterization of the prepared materials. The test results show that the [C₆VP]MoV/CA possesses the highest efficiency of 99.63% under the optimum conditions. Moreover, the catalysts can be efficiently reused with an efficiency of 85.39% after repeated use for 10 times, which confirms the industrial potential of the prepared [C₆VP]MoV/CA.

在这项工作中，设计和合成了一系列基于具有不同碳链长度的N-烷基-4-乙烯基吡啶溴化物（[C _n VP] Br）和道森型杂多酸（HMoV）的有机-无机杂化体。然后将杂化体负载在高表面积为1448.26 m ² / g的中孔碳气凝胶（CA）上，形成负载型催化剂（[C _n VP] MoV / CA），该催化剂用于萃取-氧化脱硫（EODS）。一些技术（例如FT-IR，XRD，SEM，EDX，TEM，BET和XPS）用于表征制备的材料。测试结果表明，[C ₆VP] MoV / CA在最佳条件下的最高效率为99.63％。此外，催化剂在重复使用10次后可以以85.39％的效率被有效地再利用，这证实了制备的[C ₆ VP] MoV / CA的工业潜力。
