Phosphomolybdate-based ionic liquid [(CH)NCH]PMoO was prepared and supported on a magnetic mesoporous silica (γ-FeO@SiO@mSiO) to obtain a magnetic mesoporous catalyst. The morphology and components of the catalyst were characterized by FT-IR, XRD, XPS, SEM, TEM, nitrogen adsorption-desorption isotherms, and VSM. With air as oxidant, the catalyst showed perfect desulfurization performance in oxidation of dibenzothiophene (DBT). The removal of DBT from model oil could reach 100% within 5 h at 120 °C. After reaction, the catalyst could be separated by a magnet and recycled at least four times without obvious decrease in the catalytic performance.
基于磷钼酸的离子液体[(CH)NCH]PMoO 被制备并负载在磁性介孔硅 (γ-FeO@SiO@mSiO) 上，得到一种磁性介孔催化剂。通过 FT-IR、XRD、XPS、SEM、TEM、氮气吸附-脱附等温线和 VSM 对催化剂的形貌和组成进行了表征。以空气为氧化剂，该催化剂在二苯并噻吩 (DBT) 的氧化中表现出了完美的脱硫性能。在 120°C 下，模型油中 DBT 的去除率在 5 小时内达到 100%。反应后，催化剂可以通过磁铁分离，并至少重复使用四次，而催化性能没有明显下降。
