▎ 摘　　要

NOVELTY - Method comprises embed metal ions in graphite by means of high-pressure airflow, preparing surface-modified metal material structure by high-temperature sintering in a nitrogen atmosphere and peeling graphite sheets. The preparation of graphene material modified comprises : (a) placing graphite powder in water, introducing into a stainless steel reaction vessel and 1-10% graphite powder, adding the ionic liquid with a mass concentration of 1-5%, a metal salt with a mass concentration of 10-20% and a nucleation guide agent with a mass concentration of 20-60%, Where the ionic liquid includes 1-ethyl-3-methylimidazole hexafluorophosphate, ethyltriphenylphosphine iodide, 1-octyl-3-methylimidazole tetrafluoroborate and isopropyltriphenylphosphine iodide, passing a high-speed air flow into the vessel, stir for 4 hours, washing and drying the obtained product, (ii) high-temperature sintering, sintering product in a nitrogen atmosphere at 1100-1500 degrees C for 24 hours. USE - The antibacterial and antiviral material is useful in preparing antibacterial and antiviral material. ADVANTAGE - The method is simple; the reaction is easy to control, has good stability, industrialized and has wide popularization prospect in the antiviral field. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for an antibacterial and antiviral material prepared by the method.
