چکیده مقاله:
Bimetallic nanoparticles have numerous applications in different areas, including catalysis, medicine, optics, and so on. Due to numerous intrinsic disadvantages and potentially toxic chemical procedures, finding nontoxic, green, cost-effective, and eco-friendly approaches for the production of bimetallic nanoparticles is much desired. In this study, Zn NPs, Zn/Fe۳O۴ NPs, and Zn/Chitosan/Fe۳O۴ nanocomposites were synthesized via a one-pot procedure by using leave extract of Quercus brantii, in the absence of any dangerous components. The catalytic capacity of the green synthesized Zn/Chitosan/Fe۳O۴ nanocomposite was considered for the degradation of environmental pollutants, including Congo red (CR), Methylene blue (MB), Cr(VI), and ۴-nitrophenol (۴-NP). The Zn/Chitosan/Fe۳O۴ nanocomposites have been morphologically characterized using UV–Vis, SEM, and EDX studies. The antioxidant reducing and antibacterial activities of Zn/Chitosan/Fe۳O۴ nanocomposites have been considered. Our results showed that this nanocomposite could be reused five times for removal of Congo red (CR), Methylene blue (MB), Cr(VI), and four times for reduction of ۴-nitrophenol (۴-NP), without substantial reduction in the catalytic capacity. Results showed the high potential catalytic activity of Zn/Chitosan/Fe۳O۴ nanocomposite for the reduction of organic pollutants.
