dc.description.abstractIN THIS ARTICLE, WE PROPOSE A SIMPLE PHOTOCHEMICAL METHOD TO SYNTHESIZE PURE LA2TI2O7 FLMS AND LA2TI2O7 FLMS DOPED WITH SILVER AT 1.0, 3.0, AND 5.0 MOL%. AFTER ANNEALING THE PHOTO-DEPOSITED FLMS AT 900 °C, XRD, SEM, AND XPS ANALYSES SHOWED THE FORMATION OF A MONOCLINIC LA2TI2O7 PHASE AND THE PRESENCE OF AG AND AGO IN DOPED SAMPLES. PHOTOCATALYTIC TESTS FOR CONGO RED DEGRADATION DEMONSTRATED THAT PURE LA2TI2O7 ACHIEVED 25.4% DEGRADATION, WHILE DOPED SAMPLES REACHED A MAXIMUM OF 92.7% DEGRADATION. MOREOVER, INCREASING SILVER DOPING ON LA2TI2O7 FLMS SIGNIFCANTLY REDUCED THE GROWTH OF STAPHYLOCOCCUS AUREUS, INDICATING POTENTIAL ANTIBACTERIAL PROPERTIES. THE ENHANCED PHOTOACTIVITY WAS ATTRIBUTED TO THE FORMATION OF A TYPE I HETEROJUNCTION BETWEEN LA2TI2O7 AND AGO, AND A DEGRADATION MECHANISM WAS PROPOSED BASED ON CONGO RED DEGRADATION.
