AB  - A Pt-Co(3)O(4) catalyst named Pt-Co(OH)(2)-O was prepared by metal-organic 
      templates (MOTs) conversion and used for catalytic oxidation of toluene. Through 
      the conversion, the morphology of catalysts transformed from rhombic dodecahedron 
      to nanosheet and the coated Pt nanoparticles (NPs) were more exposed. The Binding 
      energy shift in XPS test indicates that the strong metal-support strong 
      interaction (SMSI) has enhanced, and the physicochemical changes caused by it are 
      characterized by other techniques. At the same time, Pt-Co(OH)(2)-O showed the 
      best catalytic performance (T(50) = 157  degrees C, T(90) = 167  degrees C, 
      E(a) = 40.85 kJ mol(-1), TOF(Pt) = 2.68 x 10(-3) s(-1)) and good stability. In 
      addition, the in situ Diffuse Reflectance Infrared Fourier Transform Spectroscopy 
      (DRIFTS) studies have shown that because SMSI weakened the Co-O bond, the 
      introduction of Pt NPs can make the migration of oxygen in the catalyst easier. 
      The change of binding energy change and the content of various species in the 
      quasi in situ XPS experiment further confirmed that the Pt-Co(OH)(2)-O catalyst 
      has stronger SMSI, resulting in its stronger electron transfer ability and oxygen 
      migration ability, which is conducive to catalytic reactions. This work provides 
      new ideas for the development of supported catalysts and provides a theoretical 
      reference for the relevant verification of SMSI.
