▎ 摘　　要

NOVELTY - The method involves removing metal ion and residual of graphite oxide into water. A dialysis solution ultrasonic treatment is carried out by centrifugally separating to obtain suspension liquid of graphene oxide. Stannous chloride and hydrochloric acid are added to form mixed solution. Obtained composite material hydrogel is processed by de-ionized water. A drying process is carried out at temperature of 45 degree Celsius under dry condition for 72 to 96 hours to obtain macrographite alkene/tin oxide composite aerogel. USE - Method for preparing a macroscopic three-dimensional graphene/tin oxide aerogel composite material. ADVANTAGE - The method enables preparing the macroscopic three-dimensional graphene/tin oxide aerogel composite material in a simple, easy, economical and eco-friendly manner. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a macroscopic three dimensional graphene/application for tin oxide composite gas gel material. DESCRIPTION OF DRAWING(S) - The drawing shows a photograph of a macroscopic three-dimensional graphene/tin oxide aerogel composite material.
