NOVELTY - Preparing red phosphorus/graphene gas gel that can photocatalyze volatile organic compounds gas involves dissolving the commercially available micron-sized red phosphorus in the mixed solvent of deionized water, ethylene glycol and sodium hydroxide, mixing and stirring to obtain uniform mixed solution. The mixed solution is added into a Teflon-lined stainless steel reactor, and the hydrothermal reaction is carried out to obtain a nano-scale red phosphorus red gel, separating the nano red phosphorus red gel centrifuge to obtain red precipitate, and using deionized water and anhydrous ethanol for washing, washing and transferring to the blast oven to dry to obtain the dried red phosphorus, transferring the dried red phosphorus to a vacuum tubular furnace, annealing under the argon atmosphere to obtain the three-dimensional nanograde red phosphorus, taking portion of three-dimensional nano-scale red phosphorus and graphene oxide solution. USE - Method for preparing red phosphorus/graphene gas gel that can photocatalyze volatile organic compounds gas. ADVANTAGE - Graphene aerogels are prepared by mixing graphene oxide with alkyl glycosides, three-dimensional nano-red phosphorus, ascorbic acid, stearic acid, etc., in which alkyl glycosides are used as foaming agents to foam as templates, which not only can make three-dimensional structure of the graphene gel more stable, but also increases the specific surface area of graphene gas gel. The three-dimensional nano-red phosphorus/graphene gas gel can be subjected to multiple cyclic elastic tests without slag dropping and three-dimensional structure damage.
