Two surfactants with hexavanadate as polar head groups were synthesized and their amphiphilic properties were confirmed by forming emulsions in the mixture of water and nonpolar organic solvents. Due to the outstanding catalytic properties of hexavanadate, the two surfactants were utilized as 'emulsion catalysts' in ultra-deep desulfurization reactions. Their catalytic activities show a pH-dependent behavior, which can be explained by the size-change of emulsions and the appearance of reverse emulsions. The application can be extended to hazardous waste disposal, biomass conversion, and organic synthesis since the surfactants can be widely used in two-immiscible phase systems.
