“…(2014) reported that desulfurization of benzothiophene can be carried out easily at mild condition in range of temperature of 60-80 o C. Regarding the temperature being used, this repot has some slight similar finding to our work [8]. Moreover, chromatogram of oxidative desulfurization of benzothiophene using catalyst H 3 [-PW 12 O 40 ] is shown in Figure 5. This result indicate that selective desulfurization was found in our work.…”

“…For further future application of polyoxometalates as catalyst, the water of crystallization will not have an effect on the catalytic system. Figure 4 12 O 40 ] particle is seen as a block shape with small particles appeared in the surface. In this study, we found that all morphology of these polyoxometalates is affected by the synthetic technique.…”

“…However, catalyst still plays a key role for desulfurization of fuel oil. Catalyst based on polyoxometalate compounds has been investigated deeply for fuel oil desulfurization due to its beneficiary's characteristics such as acidity, oxygen transfer ability, various structures, and redox properties [9][10][11][12][13][14]. Keggin type polyoxometalate [XM 12 O 40 ]…”

In this work, the new catalyst (assigned as TBAPW11Zn@TiO2@PAni) was successfully designed and synthesized on the basis of quaternary ammonium salt of zinc monosubstituted phosphotungstate [(n‐C4H9)4N][PW11ZnO39] (TBAPW11Zn), titanium dioxide (TiO2), 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 (TBAPW11Zn@TiO2@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 TBAPW11Zn@TiO2@PAni/H2O2/CH3CO2H 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 TBAPW11Zn@TiO2@PAni nanocomposite.

Sulfur‐containing compounds are responsible for much air pollution, and therefore eliminating these compounds is of importance. Herein, a hybrid organic–inorganic recyclable nanocatalyst (TBA‐PW11Ni@PANI) was synthesized successfully to investigate its effects on the catalytic oxidative desulfurization (CODS) process of real gasoline/model fuel. To this end, the Keggin‐based mono‐lacunary polyoxometalate [PW11NiO39] was prepared and modified with quaternary cation tetrabutylammonium (TBA). Then, this was further immobilized on polyaniline (PANI) via the sol–gel method. The synthesized nanocomposite was characterized using various techniques. The high dispersion of polyoxometalate on PANI was confirmed. Also, it was found that the crystalline structure remained unaltered after immobilization. In addition, the effects of various parameters such as dosage and temperature on the CODS of model fuel in the presence of H2O2–acetic acid (1:2 v/v) were studied in detail. Moreover, the kinetics of the CODS process was also studied and a mechanism proposed. According to the results, TBA‐PW11Ni@PANI showed an efficiency of up to 97% with 0.1 g at 35°C (optimum values) which implies its good catalytic functionality in the CODS process. Finally, the TBA‐PW11Ni@PANI catalyst displayed long‐term stability and good reusability after five runs.
