The invention discloses a graphene/copper nanocrystalline composite catalytic material, which solves the problems of low loading rate, limited catalytic environment and need to improve catalytic efficiency of existing catalytic materials. The technical solution is as follows: Step 1: dissolving coniferene and copper salt in ethanol to prepare a mixed solution; ultrasonically dispersing graphene in N,N-dimethylformamide to prepare a graphene dispersion; After adding the mixed solution to the graphene dispersion to react, centrifuge, wash and freeze-dry to obtain monodispersed graphene-supported copper nanocrystals; step 2: disperse 5-10 parts by weight of graphene/copper nanocrystals in 50 parts by weight 1 part of ionized water is added, 1-1.5 weight of sodium citrate is continuously stirred for reaction, and freeze-dried to prepare porous graphene/copper nanocrystalline aerogel. The invention has simple process, easily available raw materials and low production cost, and the produced graphene/copper nanocrystalline composite catalytic material has excellent adsorption performance, long service life and high decomposition efficiency, and is suitable for various environmental conditions. |
