Liquid-phase selective oxidation of alcohols to aldehydes using molecular oxygen as an oxidant is one of the most important transformations in organic synthesis and green chemistry. In this work, nitrogen-containing ordered mesoporous materials (NOMCs) were prepared and utilized as supports to load vanadia. The physical and chemical properties of the synthesized V_xO_y/NOMC materials were characterized by N₂ adsorption–desorption, XRD, TEM, Raman, and XPS. The characterization results exhibited that NOMC could well disperse vanadia species and there was a steady interaction between V and N of NOMC. In selective oxidation of benzyl alcohol using oxygen as an oxidant, the synthesized V_xO_y/NOMC materials showed good and stable catalytic performance, affording a maximum yield of benzaldehyde up to 80% at 95 °C.

含氮有序介孔碳材料负载氧化钒催化氧选择性氧化苯甲醇

使用分子氧作为氧化剂将醇液相选择性氧化为醛是有机合成和绿色化学中最重要的转化之一。在这项工作中，制备了含氮有序介孔材料（NOMC）并将其用作负载钒的载体。通过N ₂吸附-解吸、XRD、TEM、拉曼和XPS 表征合成的V _x O _y /NOMC 材料的物理和化学性质。表征结果表明NOMC可以很好地分散钒物种，并且NOMC的V和N之间存在稳定的相互作用。在以氧为氧化剂选择性氧化苯甲醇时，合成的 V _x O _y/NOMC 材料表现出良好且稳定的催化性能，在 95°C 下苯甲醛的最大产率可达 80%。
