Calcium hydroxide loaded graphene aerogels

Calcium hydroxide loaded graphene aerogels/Ca(OH)2 loaded graphene aerogels/Calcium hydroxide loaded GO/Ca(OH)2 loaded GO from ruixi. The preparation method and application of graphene airgel composite materials loaded with calcium hydroxide belong to the technical field of graphene airgel and can solve the problems of limited absorption capacity and complicated 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 supported hydroxide is obtained. Calcium graphene airgel composite material. This composite material can be used in the field of chemical adsorption removal of acidic industrial harmful gases such as SO, HS, Cl, etc., and can also be used in the field of adsorption of VOCs gases such as benzene.
