摘　　要：采用水热法合成了纯钙钛矿钛酸铅纳米线.实验采用醋酸铅[Pb(AC)2.3H2O],钛酸四丁酯[Ti(OC4H9)4]为原料,氢氧化钠为矿化剂,研究了不同水热反应温度对产物物相及形貌的影响.当温度为200℃,反应48h,可以生成直径为10nm左右,长度在几百纳米到几微米之间的纯钙钛矿钛酸铅纳米线.Pure perovskite structure lead titanate(PT)nanowires were synthesized under hydrothermal conditions,using lead acetic and tetrabutyl titanate as the starting materials and NaOH served as a mineralizer. The effects of temperature on the morphology and crystallographic structure were discussed. The results show that PT nanowires of tetragonal perovskite with diameters about 10nm and length range from several hundreds to 5μm can be fabricated by hydrothermal method at 200℃ for 48 h.
