▎ 摘　　要

NOVELTY - Preparing graphene pyrrole aerogel involves preparing graphene oxide, and adjusting graphene oxide to 5-50 mg/ml, adding reducing agent in the graphene oxide dispersion liquid, and the volume ratio of the two is 1-10:1-10. The solution is stirred, placed in an oven at 150-200degrees Celsius, and prepared reduced graphene oxide (RGO) hydrogel by hydrothermal reaction for 1-3 hours. The RGO hydrogel is taken out, washed with water until neutral, and then freeze-dried to form RGO aerogel. The 0.1-5 vol/vol.% pyrrole aqueous solution and 0.5-5 molar ammonium persulfate hydrochloride solution are configured. The RGO aerogel is immersed in the pyrrole aqueous solution until it is completely saturated, and saturated RGO is dried, then slowly immersed in ammonium persulfate hydrochloride solution, and polymerized at 1-5degrees Celsius for 5-10 hours. The samples are washed with deionized water and dried to obtain graphene-pyrrole aerogels. USE - Method for preparing graphene pyrrole aerogel used in seawater desalination (claimed). ADVANTAGE - The method utilizes clean and sustainable energy solar energy combined with joule heat testing unit to carry out seawater desalination tests alternately and continuously, and is a novel seawater desalination method with lower energy consumption and high efficiency.
