▎ 摘　　要

NOVELTY - A magnetic graphene oxide aerogel is prepared by adding graphene oxide into deionized water, configuring to 2 mg/L graphene oxide solution, adding ferrous ferric oxide powder and phenolic resin powder, uniformly mixing to obtain magnetic graphene oxide solution, adding trisodium citrate and methyltriethylsilane, reacting to obtain magnetic graphene oxide hydrogel, cleaning, adding ammonia aqueous solution, processing in constant temperature water bath, freeze-drying, and high temperature processing. The mass ratio of ferrous ferric oxide powder and graphene oxide is 6-10:5. The mass ratio of phenolic resin powder and graphene oxide is 0.5-1.5:10. The mass ratio of trisodium citrate and graphene oxide is 2.5-3:1. The mass ratio of methyltriethylsilane and graphene oxide is 0.005-0.1:1. USE - The method is used for preparing magnetic graphene oxide aerogel. ADVANTAGE - The method is added with phenolic resin converting into amorphous carbon by high temperature carbonization, locates newly generated amorphous carbon between graphene sheet layers to increase product tensile strength, and selects sodium citrate having high efficiency and high forming rate as reducing agent.
