▎ 摘　　要

NOVELTY - Three-dimensional porous material in which walls of the pores are constituted by one or more graphene sheets with defects and pores have a distribution that includes mesopores, supermicropres, micropores, and ultramicpores. USE - Three-dimensional porous material used as carbon dioxide (CO2) adsorbent in gas separation processes, electrocatalysts, electrochemical sensors, electrodes, and catalysts and in highly suitable materials for use in supercapacitors, manufacture of lithium ion batteries (all claimed). ADVANTAGE - The three-dimensional porous material has high surface area and a significant volume of micro and ultra-micro pores, and high electrical conductivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a three-dimensional material, involves: (A) mixing a graphene precursor with a soft template agent at the concentrations required for its self-assembly in an aqueous medium or polar solvent; (B) removing the template from the material obtained; and (C) pyrolyzing the structured precursor obtained, in the absence of oxygen at a temperature between 8000-12000 degrees C.
