Role of Ag and tannin modification on photocatalytic and antibacterial properties of ZnO nanoplates

In this study, photocatalytic and antibacterial activities of ZnO, Ag/ZnO, ZnO/tannin and Ag/ZnO/tannin synthesized by microwave-hydrothermal and borohydride reduction method have been investigated. The products were characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), energy dispersive spectroscopy (EDS), fourier transform infrared (FTIR) and UV–Vis diffuse reflectance/absorbance spectroscopy (DRS). Photocatalytic activities of products were explored for the degradation of malachite green (MG) dye in presence of UV light irradiation. When photocatalytic activities of them were compared, Ag/ZnO exhibited the highest photocatalytic activity. The photodegradation efficiency of 98.68% was recorded for Ag/ZnO after 30 min. The antibacterial activities of the prepared products were examined against Escherichia coli (E. Coli), Staphylococcus aureus (S. aureus) and Candida by the well diffusion method. The results showed more excellent antibacterial activity in Ag/ZnO/tannin compared to others.
