Preparation method of magnetic graphene-based aerogel with photocatalysis function

The invention provides a preparation method of magnetic graphene-based aerogel with a photocatalysis function. The preparation method comprises the following steps: preparing a photocatalytic materialtetraamino iron phthalocyanine, then loading magnetic particles on a graphene substrate to prepare magnetic graphene-based aerogel, and finally grafting the tetraamino iron phthalocyanine to the surface of the magnetic graphene-based aerogel by virtue of amidation reaction so as to obtain the magnetic graphene-based aerogel material with the photocatalytic function. According to the invention, the material has an adsorption-degradation integrated effect and a physical magnetic separation function, can be widely applied to adsorption and degradation of a pollution system containing benzo alphapyrene (BaP), and has a potential application prospect. 本发明提出了一种光催化功能磁性石墨烯基气凝胶的制备方法，包括光催化材料四氨基钛菁铁的制备，然后在石墨烯基底负载磁性颗粒制备得到磁性石墨烯基气凝胶，最后利用酰胺化反应将四氨基钛菁铁接枝到磁性石墨烯基气凝胶表面，得到光催化功能磁性石墨烯基气凝胶材料。该材料具有吸附-降解一体功效和物理磁性分离功能，可广泛应用于含苯并α芘(BaP)污染体系的吸
