This study represents the removal of malachitegreen (MG) from aqueous solution using ZnO,Ag/ZnO, ZnO/tannin and Ag/ZnO/tannin. The products were synthesized by microwave-hydrothermal andborohydride reduction method and they were characterized by optical,structural, morphological, antibacterial and photocatalytic features. Additionally, the antibacterial studies of theprepared products were examined against Escherichia coli (E. Coli), Staphylococcus aureus (S. aureus)and Candida by the well diffusion method. Among the products, Ag/ZnO exhibits the highest photocatalytic activity.The photodegradation efficiency of 98.68% was recorded for Ag/ZnO after 30 min.Moreover, improved antibacterial activity of Ag/ZnO/tannin against E. Coli, S. aureus and Candida is observed. And it was found that Ag/ZnO/tannin hadmore excellent antibacterial activity compared to others. It has been foundthat the prepared products can be used in potential applications such decomposeof dye pollutants and destruction of pathogen bacteria and fungi.
