NOVELTY - Synthesizing porous graphene-type nanosheets using biomass as raw material comprises e.g. dissolving precursor in solvent and mixing to obtain a precursor solution, dissolving 1 g non-ionic surfactant block copolymer F127 and ultrasonically assisting to dissolve in 30 ml solvent to prepare F127 solution, adding the precursor solution in dropwise to F127 solution and magnetically stirring the whole process, cross-linking by heating and self-assembling to form composite film, uniformly mixing cross-linked film material and activator into powder, cutting the obtained film into small pieces, gradually grinding ground with an activator in an agate mortar/or mixed into a powder by ball milling, calcining the mixture under a nitrogen atmosphere, washing sample in 2 M hydrochloric acid, and then washing repeatedly with ultrapure water until a neutral pH is obtained, and then drying at 80℃ for 12 hours, and denoting the obtained sample as gel permeation chromatography (GPC)-T. USE - The method is useful for synthesizing porous graphene-type nanosheets using biomass as raw material. ADVANTAGE - The method: is simple in synthesis process, safe, expandable and green, can prepare graphene nano sheet, which has high specific surface area, macroporous volume and hierarchical porous structure, and has good conductivity.
