Biosynthesis of novel Ag@Cu alloy NPs for enhancement of methylene blue photocatalytic activity and antibacterial activity

We report the biosynthesis of Ag@Cu alloy nanoparticles (NPs) using phytochemicals as a reducing and capping agent. UV-Vis spectra shows the peak corresponding to Ag and Cu, which confirm the formation of alloy nanoparticles. The structure and morphology were measured by High Resolution-Transmission Electron Microscopy (HR-TEM), line diagram, x-ray diffraction (XRD), Fourier Transform Infrared spectroscopy and Zeta potential. The Ag@Cu alloy...
