“…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 ]…”

“…It was demonstrated that the use of TBA encapsulated cation in the catalytic framework helps in well dispersion of the catalyst in oil phase. Similar work has been carried out by Li et al recently (67), where synthesis of lacunary PW 11 encapsulated into mesoporous silica pillared in clay interlayer galleries has been discussed for ODS of DBT as model oil as a probe reaction. Catalytic performance of all the materials showed no significant decrease in the conversion rate after four runs.…”

In this article we discussed synthesis and catalytic applications of heterogeneous catalysts based on lacunary polyoxometalates (LPOMs) and transition metal substituted polyoxometalates (TMSPOMs), however exclusively the focus has been given to the mono LPOMs and mono-TMSPOMs. As the field of supported LPOMs/TMSPOMs is upcoming important field, some aspects about choice of support as well as methods of supporting have also been described. We also include a few of our new research results in order to understand the effect of support and active species as well as choice of organic transformation. ARTICLE HISTORY

An ammonium salt of molybdenum heteropoly acid was loaded on silica support (HPA-SiO2), used as catalyst in oxidative desulfurization for removing benzothiophene (BT), dibenzothiophene (DBT) and 4,6-dimethyldibenzothiophene (4,6-DMDBT) from model oil. The structural properties of prepared catalyst were studied by using various analytical techniques; Fourier transforms infrared spectroscopy , X-ray diffraction, scanning electron microscopy and thermogravimetric analysis. The results showed that the ammonium salt of molybdenum heteropoly acid highly dispersed on SiO2. The final catalyst exhibits good catalytic activity of oxidative desulfurization. The 94.6 % of thiophene compounds of the model oil were removed under optimal conditions; temperature at 80 °C, reaction time 100 min. The oxidation is decreased in order of DBT > 4,6-DMDBT > BT.
