▎ 摘 要
The graphene sheets were modified and separated by S based groups; sheets seldom form a conventional reduced graphene oxide structure. The more disorganised the sheet stack, the more mesopores and macropores they form. Sulphur based groups and residual oxygenated functional groups effectively improve pore size. The products show promising performance in water purification. Adsorption data indicated that the porosity and binding site had remarkable influence on the adsorption capacity than high surface area.
