Zusammenfassung:	The invention belongs to the technical field of preparation and application of biomass nanomaterials, and discloses litchi shell-based carbon dots with antibacterial and antioxidant activity as well as a preparation method and application of the litchi shell-based carbon dots. According to the method, the carbon dots are prepared from dried and smashed litchi shells through a one-step hydrothermal method, the surfaces of the litchi shell-based carbon dots are rich in a large number of phenolic light groups, alcohol and aldehyde functional groups and other structures, so that the carbon dots have high oxidation resistance, meanwhile, the antibacterial activity of the carbon dots is excellent, and the carbon dots have a good antibacterial effect on staphylococcus aureus and escherichia coli; in addition, the carbon dots have a good antibacterial effect in botrytis cinerea and also have good time stability, pH value stability and salt stability, experiments prove that the carbon dots can be integrated into food
