Preparation method and application of surface iron oxide graphene co-loaded zero-valent iron particle material

The invention provides a preparation method and application of a surface iron oxide and graphene co-loaded zero-valent iron particle material, and belongs to the technical field of environmental restoration and material preparation. The preparation method of the material comprises the following steps: firstly preparing a zero-valent iron particle material with a clean surface, then preparing graphene oxide with a large number of oxygen-containing functional groups by using a chemical oxidation method, and finally co-loading iron oxide and graphene on the surface of zero-valent iron through a reduction reaction to obtain the surface iron oxide and graphene co-loaded zero-valent iron particle material. According to the reduction loading method, graphene and iron oxide are firmly combined on the surface of zero-valent iron through covalent interaction, the electrochemical activity and stability of the surface of the material are greatly improved, the iron oxide with high conductivity and magnetism can be specifi
