Three kinds of new layered perovskite compounds with Ruddlesden-Popper(R-P)phase,Ag_xNa_(2-x)La_2Ti_3O_(10)(x=0.2,0.3 and 0.5),were synthesized by an ion-exchange reaction of Na_2La_2Ti_3O_(10)with AgNO_3 solution.The structures of the compounds were characterized by EDX and XRD,and their antibacterial activity and light-resistance property were evaluated.The results indicated that the molecular formula of Ag_xNa_(2-x)La_2Ti_3O_(10)(x=0.2,0.3 and 0.5)was confirmed,and that the crystalline structure of Na_2La_2Ti_3O_(10)was not obviously affected by exchange of silver ion.The minimum inhibitory concentrations(MICs)of Ag_(0.3)Na_(1.7)La_2Ti_3O_(10)against Escherichia coli(E.coli),Staphylococcus aureus(S.aureus)were 180μg/mL and 240μg/mL, respectively,while its discoloration was not observed after 24 h light ageing test.
