Facile and one-step liquid phase synthesis of uniform silver nanoparticles reduction by ethylene glycol

A facile, simple to synthesis uniform and monodisperse, well size distribution of silver nanoparticle with 20-30 nm was reported. The silver nanoparticles were successfully synthesis by liquid phase method of EG (Ethylene glycol) in the presence of PVP (Polyvinyl pyrrolidone). The properties of uniform silver nanoparticles were investigated by HRTEM (High resolution transmission electron microscope), SEM (Scanning electron microscope), UV-vis (UV-visible spectroscopy), FT-IR (Fourier transform infrared spectra) and XRD (X-ray diffraction). The effects of different reaction conditions on the size distribution of Ag NPs were studied. The XRD peaks are consistent with the data on the standard card, corresponding to the face-centered cubic Ag plans of (111), (200), (220), (311) and (222). Besides, the d-spacing of silver nanoparticle is d = 0.223 nm by measuring the distance between the planes, which is in agreement with the value of the (111) lattice spacing of FCC (face centred cubic) silver. The research results would be useful to assess the facile synthesis of uniform and monodisperse silver nanoparticles.
