AB  - To preparation of ultra-clean gasoline fuel, a new amphiphilic nanocomposite 
      (TBA-SiWMn@PVA) has been successfully synthesized by supporting sandwich-type 
      silicotungstate polyoxometalate ((n-C(4)H(9))(4)N)(7)H(5)Si(2)W(18)Mn(4)O(68) 
      (TBA-SiWMn) on polyvinylalcohol (PVA) as an efficient catalyst for catalytic 
      oxidative desulphurization (CODS) of gasoline. The synthesized materials were 
      characterized by means of elemental analysis, (113)Mn NMR, (29)Si NMR, XRD, SEM, 
      FT-IR and UV-vis techniques. The catalytic activity of TBA-SiWMn@PVA 
      nanocomposite was tested on real gasoline in the presence of CH(3)COOH/H(2)O(2) 
      as an oxidant and the results were compared with model sulphur compounds at the 
      same conditions. The TBA-SiWMn@PVA nanocomposite was shown excellent catalytic 
      performance and recoverability for ODS of gasoline with high yield. The effects 
      of the reaction time, reaction temperature, dosage and nature of catalyst were 
      investigated. The reaction mechanism and the kinetic parameters of sulphur 
      compounds oxidation were also discussed. The probable mechanism was proposed via 
      the electrophilic mechanism through the formation of a peroxometalate 
      intermediate complex with phase transfer properties. Results were indicated that 
      the kinetics of sulphur oxidation fitted the pseudo-first-order kinetic model. 
      After 5 oxidation runs, the heterogeneous nanocatalyst was separated and 
      recovered easily.
