由于对燃油硫含量的控制日益严格,氧化脱硫（ODS）作为一种前景广阔的脱硫技术需要不断发展.本工作将构建多孔结构、提升磷钼酸（PMo）的负载量、提高两亲性以及利用载体的还原框架提高PMo的本征活性等策略整合实施,成功制备了具有出色ODS催化能力的PMo@Pa.-54材料.在催化剂制备过程中,Pa.-54不是简单地作为载体与PMo发生物理的结合,更是与PMo发生了电子转移,生成了具有更优催化活性的Mo5+.Pa.-54的存在使PMo的催化活性得到了质的飞跃,实现了快速且高效的脱硫.我们还发现其他富氮多孔有机聚合物也可在负载过程中还原PMo中的部分Mo6+,并对其反应机理进行了探索研究.本工作为设计高效的ODS催化剂提供了一个切实可行的策略.
