Abstract
AgFeO2 delafossite was successfully prepared by a facile and low-cost method which was flash auto-combustion technique. X-ray diffraction pattern (XRD) confirmed that the sample was in the nanosize range. Also, the morphology analyzed by high resolution transmission electron microscopy (HRTEM) and field emission scanning electron microscopy (FESEM) clarified that AgFeO2 delafossite was in the nanoscale range. The composition of the sample was determined using energy dispersive X-ray (EDX) analysis. The magnetic properties assured that the sample had ferromagnetic behavior. The optical properties were measured for the investigated sample and the energy gap was 3.4 eV. The antimicrobial activities were screened against Gram positive and Gram negative bacteria and the results revealed a strong antibacterial activity of AgFeO2 delafossite. Moreover, Fungi activity was studied against Aspergillus flavus and Candida albicans and the results revealed that no activity by adding AgFeO2 delafossite had happened. The application of this study promotes the use of AgFeO2 as antibacterial agent.
