Abstract
An aqueous carbon dioxide foam stabilized by organic Janus nanosheets, a preparation method and application thereof. The preparation method can be provided as: S1: subjecting molecules with hydrophobic tail to spontaneous and ordered arrangement in a mixture of ethanol and water; S2: adding molecules with hydrophilic head to the solution of S1, and adjusting a pH value to 6.0-6.5 to perform a synthesis of organic Janus nanosheet monomers; S3: adding ethanol to the solution of S2, and adjusting the pH value to 6.0-6.5 to perform a heating reflux; then adjusting the pH value to 7.0-8.0, and adding sodium ethylate, adjusting a temperature to 70-85° C. to perform a reaction under an inert atmosphere, and then adjusting the pH to 8.0-9.0, and stirring to be completely dissolved. The aqueous COfoam is prepared from COand a liquid phase.
