摘　　要：采用溶液法制备了较高长径比 (～ 1 0 0 )的铅的均匀纳米线及纳米粒子 ,并对产物进行了 XRD,SEM和 TEM表征 .探讨了反应温度、反应物浓度及还原剂种类对产物成相及形貌的影响 ,初步讨论了铅钠米线的形成机制 .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.
