The invention discloses a rGO/Mg(OH)2 photocatalytic reactor with activated carbon fiber cloth as a carrier. The preparation method: (1) preparation of GO: preparation by improved Hummers method; (2) preparation of rGO/Mg(OH) 2 composite Materials: Using chemical precipitation method, using GO and MgCl 2 6H 2 O as initial raw materials, reducing GO with green reducing agent, and then adjusting the content of GO and reaction time to make Mg(OH)2 nanosheets evenly dispersed in the rGO nanosheets to obtain rGO/Mg(OH)2 composite materials; (3) Preparation of activated carbon fiber cloth: using viscose polyester and cotton blended fabrics, prepared by opening, carding, air-laid, carbonization and activation technologies, and then Pretreatment of the surface of activated carbon fiber cloth; (4) Preparation of rGO/Mg(OH)2 photocatalytic reactor with the above cloth as the carrier: the impregnation-pulling method is used to make the rGO/Mg(OH)2 composite material loaded on the surface of the carrier to prepare a photocatalytic reactor. catalytic reactor. The invention makes high-value utilization of waste resources, at the same time endows the material with photocatalytic properties, realizes the immobilization of powdery photocatalytic materials, and has good application prospects in the field of environmental treatment. |
