▎ 摘  要

NOVELTY - Preparing three-dimensional porous graphene/attapulgite composite aerogel comprises using modified Hammers method to prepare a graphene oxide dispersion solution, modifying attapulgite to obtain uniform attapulgite suspension, mixing graphene oxide dispersion solution and attapulgite suspension, stirring uniformly, self-assembling the obtained mixed solution under low temperature wet chemical reaction conditions to obtain a composite hydrogel, washing the composite hydrogel and freeze-drying to obtain the product. USE - The composite aerogel is useful in treating pollutants and wastewater. ADVANTAGE - The composite aerogel: has three-dimensional multi-stage pore structure, high specific surface area of 5-500 m2/g and channel diameter of 1-10 mu m (claimed). The method: is simple, economical; and provides technical reference for developing high-performance attapulgite-based adsorbent materials. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for three-dimensional porous graphene/attapulgite composite aerogel.
