摘　　要：本文介绍一种用电化学还原法制备氧化铅纳米棒的简单方法。实验中所用的电解液是混有氧氯化锆和三氯化钛的硝酸铅溶液,采用不锈钢片作为阴极和基底。在室温下,由直流电源供电,通过控制输出电流的大小在不锈钢片基底上沉积产物。氧化铅纳米棒的产生与电流密度有关,通过讨论,得出生成氧化铅纳米棒的最佳电流密度大小。用SEM、TEM、EDS和XRD对产物进行了表征。研究结果表明,所制备的氧化铅纳米棒是单晶结构。A simple method to fabricate lead oxide nanorods by an electrochemical reduction was reported. In the experiment, the electrolyte was lead nitrate aqueous solution containing zirconium oxide chloride and titanium （ Ⅲ ） chloride solution. Stainless steel plate was employed as both cathode and substrate. The controlled current that was supplied by a DC power supply passed through the electrolyte to deposit lead oxide nanorods on the surface of stainless steel at room temperature. The yield of lead oxide nanorods was affected by the current density. So the impact of the current density on the yield of lead oxide nanorods was discussed in order to find the optimal current density for the fabrication of lead oxide nanorods. The as-synthesized products were characterized by SEM, TEM, EDS and XRD. The results of characterization indicated that the lead oxide nanorods were single crystals.
