In order to obtain the deep desulfurization in the extractive catalytic oxidative desulfurization (ECODS) system, the evaporation-induced self-assembly (EISA) assisted by cash (combined assembly by soft and hard chemistry) method was applied to prepare mesoporous Mo–Al oxides with the stable catalytic performance when the acetonitrile as the extractant and H₂O₂ as the oxidant. Their physical chemical properties were also characterized by XRD, N₂ sorption, FT-IR, SEM–EDX, H₂-TPR, and Raman techniques. The characterization results indicated that tetrahedral molybdenum species can be highly dispersed into the meso-structure of γ-Al₂O₃, and the stronger interactions would be formed for 25Mo–Al catalyst than the 25Mo–Al–C catalyst prepared by impregnation method resulting in their superior physical chemical properties although the molybdenum species is the same. The 25Mo–Al catalyst showed higher desulfurization ratio than other xMo–Al catalysts and its value can be reached up to 100% at the molar ratio of H₂O₂ to dibenzothiophene (DBT) 2.3, volume ratio of oil phase to acetonitrile 3, catalyst dosage 0.012 g/mL, reaction temperature 60 °C and reaction time 30 min. The 25Mo–Al catalyst also showed good stability even after reaction for 10 recycles.

为了在萃取催化氧化脱硫（ECODS）系统中获得深度脱硫，采用现金辅助（软硬结合组装）的蒸发诱导自组装（EISA）方法制备了介孔Mo-Al氧化物以乙腈为萃取剂，H ₂ O ₂为氧化剂，具有稳定的催化性能。它们的物理化学性质还通过XRD，N ₂吸附，FT-IR，SEM-EDX，H ₂ -TPR和拉曼技术表征。表征结果表明四面体钼物种可以高度分散到的内消旋结构的γ-Al ₂ ö ₃，并且较强的相互作用将用于形成25 Mo-Al催化剂比通过浸渍法制备的25 Mo-Al-C催化剂具有更好的物理化学性能，尽管钼的种类相同。的25的Mo-A1催化剂显示出更高的脱硫率比其他X沫-铝催化剂和它的值可以在H的摩尔比来达到最高100％₂ Ò ₂到二苯并噻吩（DBT）2.3，乙腈油相的体积比3，催化剂用量为0.012g / mL，反应温度为60℃，反应时间为30分钟。的25的Mo-A1催化剂还甚至10个再循环反应后表现出良好的稳定性。
