Summary: | Proanthocyanidins-functionalized Au/Ag bimetallic nanoparticles were synthesized by a hydrothermal method. The obtained Au/Ag nanoparticles have been characterized by UV-Vis absorption spectra (UV), Fourier transform infrared spectroscopy (FTIR), Transmission electron microscopy (TEM) and X-ray diffraction (XRD). The UV and FTIR measurement indicated that the as-synthesized colloids have the spherical shapes and the presence of the polymerized proanthocyanidins around metal nanoparticles. TEM and XRD results revealed that the nanoparticles have uniform core-shell structures and the metal core possessed a highly crystalline structure. Furthermore, it was found that the proanthocyanidins-functionalized Au/Ag bimetallic nanoparticles have high removal efficiency for some organic dyes. |
