▎ 摘　　要

NOVELTY - A modified activated carbon material comprises activated carbon particles and graphene sheet layer adsorbed on the activated carbon particles. USE - Modified activated carbon material is useful as adsorbent for processing water and desalinating seawater and water and electrode material of supercapacitor (claimed). ADVANTAGE - The modified activated carbon material has high specific surface area and excellent adsorption effect, conductivity and dispersibility. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of modified activated carbon material, which involves activating activated carbon, adding graphene material and then mixing, adding crosslinking agent and then polymerizing and crosslinking.
