Using molecular oxygen as oxidizing agent, deep oxidative desulfurization of fuels containing sulfur compounds has always been a rather vital research subject. In our research, few-layer and single-layer h-BN will be designed and synthesized, which are coated with metal macrocycle-containing redox ionic liquids. These novel catalysts are used to investigate the activity on deep oxidative desulfurization of fuels in the presence of oxygen. From multilayer to few-layer and single-layer, the change rule and the reason for such change of h-BN carrier will be researched. Study the influence of ionic liquid structure and loading ionic liquid method to grapheme-like h-BN specific surface area , surface wettability loading stability and durability, specific surface wettability, associating its oxidation desulfurization activity. The investigation of in situ spectra and electrochemistry experiments is used to provide ground for redox activity and oxidative desulfurization mechanism. The recycling and regeneration of graphene-like h-BN supported redox ionic liquid will be researched. In the process of oxidative desulfurization, the novel catalysts possess the extractive character of ionic liquids and high specific surface area and single molecular layer of graphene-like h-BN, which can activate oxygen. So this research may provide a new method for deep oxidative desulfurization of fuels.
