Carbon materials have large specific surface areas and tunable pore size distributions,which make them potential adsorption and catalytic materials.In recent years,carbon materials have been widely used in the field of deep desulfurization.The research progress of carbon and its composites in the fields of catalytic hydrodesulfurization,adsorption desulfurization,and oxidative desulfurization is reviewed.In hydrodesulfurization,the adjustment of the electronic structure of the catalyst and the effect on the hydrodesulfurization activity brought by combination of carbon and traditional catalytic materials are described in detail.In adsorption desulfurization,the preparation and modification of carbon materials by heteroatom doping are emphasized,as well as the advantages and disadvantages of carbon as adsorbents.In oxidative desulfurization,the mechanisms of carbon as catalyst for oxidative removal of sulfide are summarized.Finally,the main problems for desulfurization by carbon are proposed to provide references for the development of carbon materials.
