Mesoporous, multi-valent tungsten oxide with high surface area (209 m²/g) is synthesized via a novel metal dissolution coupled with reverse micelle formation approach. Mesoporous tungsten oxide with highest surface area reported is obtained by this method. The material is used as an excellent heterogeneous catalyst for the oxidation of organosulfur compounds present in crude oil. The complete oxidation of dibenzothiophene was observed with excellent yield (>99%) within 15 min at room temperature (20 °C). The catalyst is reusable up to 5 reaction cycles without losing significant activity. A green oxidant, H₂O₂ is used and the reaction mechanism involves the activation of peroxo species by W⁶⁺. The oxidation activity decreases in the order of DBT > 4,6-DMDBT > 1-BT due to the changes in the electronic environment of sulfur and steric effects.

通过新颖的金属溶解与反胶束形成方法合成具有高表面积（209 m ² / g）的中孔多价氧化钨。通过这种方法获得了具有最高表面积的介孔氧化钨。该材料用作氧化原油中存在的有机硫化合物的出色多相催化剂。在室温（20°C）下15分钟内观察到二苯并噻吩的完全氧化，收率极佳（> 99％）。该催化剂可重复使用多达5个反应周期，而不会失去明显的活性。使用绿色氧化剂H ₂ O ₂，反应机理涉及W ⁶⁺对过氧物质的活化。由于硫的电子环境的变化和位阻效应，氧化活性以DBT> 4,6-DMDBT> 1-BT的顺序降低。
