Research progress of 2D layered materials for fuel oil oxidation desulfurization
Two dimensional(2D)layered materials are widely used in the field of oxidative desulfurization of fuel oil due to their unique properties,such as graphene and other graphene-like materials(such as graphitic carbon nitride and hexagonal boron nitride),2D silicon-based materials,layered double hydroxides,MXene,2D metal-organic frameworks,molybdenum disulfide,etc.Starting from different 2D layered materials,this paper summarized how to build catalytic oxidation desulfurization catalysts,catalyst desulfurization efficiency,desulfurization process and mechanism,and combed the research status of 2D layered materials in the field of oxidative desulfurization.Nevertheless,most ordinary 2D layered materials cannot be directly applied to fuel oil oxidation desulfurization process because of their insufficient catalytic performance.Therefore,researchers modified 2D layered materials by manufacturing defects,element doping,functional group modification and loading active sites,and applied them to catalytic oxidation desulfurization process.Finally,this article presentes prospects for the research direction of 2D layered materials in the field of oxidative desulfurization,and pointes out that constructing 2D layered oxidative desulfurization catalysts with controllable and open 2D transport channels was one of the important directions for future research in the field of desulfurization.
