▎ 摘　　要

NOVELTY - A graphene-porous ceramic composite adsorbent material comprises porous ceramic substrate in which porous ceramic substrate is internally loaded with graphene. USE - A graphene-porous ceramic composite adsorbent material for treatment of wastewater. ADVANTAGE - Process is environment-friendly, low cost, and simple, and product is recyclable and has improved dirt adsorption capacity and acid and alkali resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene-porous ceramic composite adsorbent material which involves dissolving small organic molecule and/or large organic molecule to obtain soaking solution, soaking porous ceramic substrate, internally loading small organic molecule and/or large organic molecule into porous ceramic substrate, sintering into sintering device under atmospheric condition, and converting loaded small organic molecule and/or large organic molecule into graphene. DESCRIPTION OF DRAWING(S) - The drawing shows a scanning electron microscope image of blank porous ceramic substrate.
