Porous graphene was a family of porous carbon with three-dimension network structures,which was prepared based on graphene with two-dimension tructures.Porous graphene possesses some natural properties of grapheme,and larger surface area as well as abundant pores.These nanopores facilitate transportation and separation of molecules,which makes the porous graphene and porous graphene based nanocomposites potential in nanoparticles loading,transportation,absorption and separation etc.The synthesis method of porous graphene including activation method,freeze-drying method,hard and soft template method,as well as deposition method were reviewed.Besides,the applications and outlook of porous graphene in supercapacitors,Li-O2 cells,absorption and separation were introduced.
