| Abstract: | A solution-based method was developed to obtain Pb nanowires in diameters of 70—120 nm and lengths up to~40 μm. Pb nanoparticles in diameter of 10—100 nm were also received under specific conditions. The products were characterized by XRD, SEM, and TEM. Based on the morphology and size evolution of products as varying reaction temperature, reactant concentration, as well as reaction time, the growth mechanism for Pb nanowires was suggested. Different reductants, such as diethyl glycol and hydrazine hydrate, were also compared. |
