Graphene aerogel composites loaded with calcium hydroxide

Calcium hydroxide-loaded graphene(GE) aerogel composite is a new material that combines the excellent properties of calcium hydroxide and graphene aerogel. Calcium hydroxide, as a common inorganic compound, has a wide range of applications in many industrial fields, especially in the environmental protection field, such as for treating acidic gases and adsorbing VOCs (volatile organic compounds). Graphene aerogel, with its high specific surface area, porous structure and excellent conductivity, provides good support and performance foundation for composite materials. A preparation method and application of a calcium hydroxide-loaded graphene airgel composite material, which belongs to the technical field of graphene airgel and can solve the problems of limited absorption capacity and complex production process of existing industrial harmful gas treatment and absorption methods. The invention adopts a step-by-step synthesis method. First, the precipitation method is used to synthesize calcium hydroxide particles, and the electrolytic oxidation method is used to synthesize graphene oxide. In the next step, the hydrothermal synthesis method is used to polymerize calcium hydroxide and graphene oxide, and finally the load is obtained. Calcium hydroxide graphene airgel composite material, this composite material can be used for SO.
