▎ 摘  要

NOVELTY - Preparing graphene silver-carrying aerogel comprises (1) mixing and fully dispersing 28-48 pts. wt. graphene oxide and 7-12 pts. wt. deionized water to obtain a graphene oxide dispersion, (2) adding 30-50 pts. wt. melamine to the graphene oxide dispersion and stirring uniformly to obtain a mixed solution, (3) providing 2.4-3.6 pts. wt. silver nitrate and dissolve in 1.2-1.8 pts. wt. water to prepare silver nitrate solution, and adding the silver nitrate solution to the mixed solution, stirring it evenly, sealing and performing a hydrothermal reaction at 95-180degreesC for 6-12 hours to obtain the crude product of graphene-loaded silver hydrogel, and (4) washing the crude graphene silver-carrying hydrogel prepared with deionized water several times to remove impurities therein, and then drying to obtain a graphene-silver-carrying aerogel. USE - The method is useful for preparing graphene silver-carrying aerog, which is usedin the reduction treatment of p-nitrophenol organic dyes in industrial wastewater (claimed). ADVANTAGE - The method is simple, economical, and less noble metal silver consumables. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a graphene silver-carrying aerogel.
