【摘要】Three kinds of new layered perovskite compounds with Ruddlesden-Popper (R-P) phase, AgrNa2-xLa2Ti3O10 (x = 0.2, 0.3 and 0.5), were synthesized by an ion-exchange reaction of Na2La2Ti3O10 with AgNO3 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 AgxNa2-xLa2Ti3O10 (x = 0.2, 0.3 and 0.5) was confirmed, and that the crystalline structure of Na2La2Ti3O10 was not obviously affected by exchange of silver ion. The minimum inhibitory concentrations (MICs) of Ag0.3Na1.7La2Ti3O10 against Escherichia coli (E. coli), Staphylococcus aureus (S. aureus) were 180 μg/mL and 240 μg/mL, respectively, while its discoloration was not observed after 24 h light ageing test.
