Summary:The invention discloses a high-bulk-density graphene/Ag-TCNQ composite material, a preparation method and application, a two-dimensional graphene hydrogel film is used as a carrier, zero-dimensional Ag-TCNQ quantum dots are loaded on the carrier, and the preparation method comprises the following steps: carrying out suction filtration on reduced graphene to form a film; putting the membrane into a mixed solution of water and N-methyl pyrrolidone for exchange; putting the materials into a silver nitrate solution, standing for a period of time, and then soaking in clear water for storage; and adding the material into an acetonitrile solution containing an organic ligand 7, 7, 8, 8-tetracyano-p-benzoquinone dimethane, continuously standing for a period of time, and cleaning the surface with acetonitrile to obtain the composite material. The material shows good electrocatalytic oxygen reduction performance, the electron transfer number in the electrochemical reaction process can be regulated and controlled by reg
