Phosphotungstic acid-loaded zirconium dioxide (HPW@ZrO₂) nanoparticles with excellent oxidative desulfurization performance were prepared and fully characterized. By employing this material as oxidative desulfurization catalyst, removal of DBT from 1000 ppm of simulated oil can be completed within 20 min under the optimal conditions. After 5 recycling cycles, DBT removal rate was not obviously decreased, indicating the good recyclability of the catalyst. In addition, this material also exhibited good desulfurization performance for gasoline. The successful preparation of HPW@ZrO₂ nanocomposite provides an alternative option for catalytic oxidative desulfurization in the production of clean fuel.

制备并充分表征了具有优异氧化脱硫性能的磷钨酸负载二氧化锆（HPW@ZrO ₂）纳米颗粒。采用该材料作为氧化脱硫催化剂，在最佳条件下可在20分钟内完成1000ppm模拟油中DBT的脱除。5个循环循环后，DBT去除率没有明显下降，表明催化剂具有良好的可循环性。此外，该材料对汽油也表现出良好的脱硫性能。HPW@ZrO ₂纳米复合材料的成功制备为清洁燃料生产中的催化氧化脱硫提供了一种替代选择。
