Graphite carbon nitride was modified by chitosan as matrix material.Ag-Cu2O/Chitosan/g-C3N4(Ag-Cu2O/CTS/CN) was prepared by using ascorbic acid as reducing agent,Cu(NO3)2·3H2O,AgNO3,as raw materials via hydrothermal and microwave method.Antibacterial property was investigated by the testing of minimum bactericidal concentration (MBC) and minimum inhibitory concentrations(MIC).The effect of different proportion of silver and copper content on the photocatalytic and antibacterial properties were discussed.It was found that the Ag-Cu2O/CTS/CN(1∶2) showed best photocatalytic activity and antibacterial performance under visible light,with MIC100%Ag of 7.78×10-6 and MBC100%Ag of 3.89×10-6.Better antibacterial performance was obtained by decreasing the content of silver.
