In this research, micro-mesoporous SiO₂ aerogel was used as support with different percentages of MoO₃ and evaluated simultaneously as a catalyst for oxidation of dibenzothiophene (DBT) and as an adsorbent for oxidation products. Among studied weight percentages of MoO₃, the SiO₂ aerogel-supported catalyst with 1.5 wt% of MoO₃ indicated the higher decline in C/C₀ of DBT after 60 min (0.06). The characterization of the as-prepared catalysts by XRD, FESEM, EDX, FTIR, BET-BJH, and TEM indicated that MoO₃ nanoparticles were uniformly dispersed on the surface of silica aerogel at all studied percentages. Despite a regular reduction in porosity with increasing MoO₃ content, catalytic activity in DBT oxidation enhanced due to enhancing MoO₃ content, amount of active sites, and hydrophilicity of surface for adsorbing H₂O₂, which is dissolved in water. Successive runs of oxidative-adsorptive desulfurization confirmed the stability of the MoO₃–SiO₂ aerogel catalyst. Examination of spent catalyst indicated that while crystalline structure remained unchanged, the porosity of spent catalyst decreased due to adsorption of DBT sulfones on the surface. In the following Iranian gasoil was subjected to the novel method of desulfurization and the GC-MS result indicated a noticeable reduction in sulfur-containing components of fuel after desulfurization.

在这项研究中，微介孔 SiO ₂气凝胶被用作具有不同百分比的 MoO ₃的载体，并同时作为二苯并噻吩 (DBT) 氧化的催化剂和氧化产物的吸附剂进行评估。之间的MoO的研究的重量百分比₃中，SiO ₂与的MoO的1.5％（重量）气凝胶担载催化剂₃表示在C / C的较高下降₀之后60分钟（0.06）DBT的。通过 XRD、FESEM、EDX、FTIR、BET-BJH 和 TEM 表征所制备的催化剂表明 MoO ₃纳米粒子以所有研究的百分比均匀分散在二氧化硅气凝胶的表面。尽管孔隙率随着 MoO ₃含量的增加而有规律地降低，但由于提高了 MoO ₃含量、活性位点的数量以及吸附溶解在水中的H ₂ O ₂的表面的亲水性，DBT 氧化的催化活性增强。氧化吸附脱硫的连续运行证实了 MoO ₃ -SiO ₂的稳定性气凝胶催化剂。对废催化剂的检查表明，虽然晶体结构保持不变，但由于 DBT 砜吸附在表面，废催化剂的孔隙率降低。在接下来的伊朗瓦斯油中进行了新的脱硫方法，GC-MS 结果表明脱硫后燃料的含硫成分显着减少。
