Venturello‐structured polyoxometalates (POMs) are effective homogeneous catalysts and confining POMs to size‐matched metal‐organic frameworks (MOFs) as heterogeneous catalyst is an effective way to improve their practical application. The appropriate pore and narrow window of pristine UiO‐67 can not only enclose POMs in single molecule but also limit their leaching and can provide a suitable platform for the oxidation of most sulfur‐containing organic compound. The composite (CTA) 3 PW 4 @UiO‐67 was prepared by a facile in situ synthesis method, characterized by a variety of means and tested for desulfurization of multicomponent simulated diesel. The results prove that the active component (CTA) 3 PW 4 is effectively encapsulated, and the composite (CTA) 3 PW 4 @UiO‐67 show remarkable desulfurization activity and excellent reusability. In addition, the kinetics and possible mechanism of the reaction were investigated. This work opens up a new idea for the design of “host‐guest adapted” catalyst suitable for fuel desulfurization technology.
