Abstract

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)₃PW₄@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)₃PW₄ is effectively encapsulated, and the composite (CTA)₃PW₄@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.

期刊介绍： All new compounds should be satisfactorily identified and proof of their structure given according to generally accepted standards. Structural reports, such as papers exclusively dealing with synthesis and characterization, analytical techniques, or X-ray diffraction studies of metal-organic or organometallic compounds will not be considered. The editors reserve the right to refuse without peer review any manuscript that does not comply with the aims and scope of the journal. Applied Organometallic Chemistry publishes Full Papers, Reviews, Mini Reviews and Communications of scientific research in all areas of organometallic and metal-organic chemistry involving main group metals, transition metals, lanthanides and actinides. All contributions should contain an explicit application of novel compounds, for instance in materials science, nano science, catalysis, chemical vapour deposition, metal-mediated organic synthesis, polymers, bio-organometallics, metallo-therapy, metallo-diagnostics and medicine. Reviews of books covering aspects of the fields of focus are also published.
