With increasing stringent standard of sulfur content in fuels, deep desulfurization with high-efficiency is necessary for ecological and environmental demands. Herein, vanadium-substituted polyoxometalate-based ionic liquids with tunable electrophilicity were facilely synthesized through ion exchange method, and applied in the aerobic oxidative desulfurization. The experimental results indicated that both imidazole cation and polyoxometalate anion played a vital role in the desulfurization process. The prepared materials have a good performance on the degradation of aromatic sulfur compounds, which can reach up to 98.9 % under optimal conditions. Moreover, the structure-function relationship was also investigated in detail, as well as the proposed mechanism.
