In this work, the new catalyst (assigned as TBAPW 11 Zn@TiO 2 @PAni) was successfully designed and synthesized on the basis of quaternary ammonium salt of zinc monosubstituted phosphotungstate [( n ‐C 4 H 9 ) 4 N][PW 11 ZnO 39 ] (TBAPW 11 Zn), titanium dioxide (TiO 2 ), and polyaniline (PAni). This study reports the catalytic oxidation‐extraction desulfurization (ECODS) of sulfur‐containing molecules from real and the simulated (Th, BT, and DBT) gasoline using new organic–inorganic hybrid catalyst (TBAPW 11 Zn@TiO 2 @PAni). The ECODS results were shown that the concentration of sulfur compounds (SCs) of real gasoline was lowered from 0.4992 to 0.0122 wt.% with 97% efficiency at 35 °C after 1 h. Furthermore, the synthesized heterogeneous nanocatalyst showed high stability and reusability after five times without significant loss of activity. The high performance of TBAPW 11 Zn@TiO 2 @PAni/H 2 O 2 /CH 3 CO 2 H system can be a promising route with a superb potential in the generation of ultra‐low‐sulfur gasoline. Also the Mann–Whitney U‐test results show that there is not a significant difference between the mean of sulfur percentage for DBT & BT, BT & Th and DBT & Th in the presence of the catalyst. Based on the Kruskal–Wallis test results, we can conclude that the temperature, time and amount of catalyst have a significant effect on ECODS efficiency of TBAPW 11 Zn@TiO 2 @PAni nanocomposite.
