Description

technical field [0001] The invention relates to a graphene-supported nano ZnO / Ag composite material and a preparation method thereof, belonging to the field of composite materials. Background technique [0002] In the field of material science, composite materials complement each other in performance and produce synergistic effects, showing great application prospects in many fields such as industry and biomedicine. Studies have found that both silver nanoparticles and zinc oxide nanoparticles have good antibacterial activity, but the preparation of silver nanoparticles is expensive and the cost is high. Nano-ZnO micropowder has superior antibacterial, disinfection, deodorizing functions and adsorption properties, but as a semiconductor material, ZnO has poor electrical conductivity, and the probability of recombination of photogenerated electrons and holes is high, which affects the antibacterial catalytic effect. Graphene is a two-dimensional carbon atom crystal with a si...
