摘　　要：以亚硒酸为硒源,以葡萄糖为还原剂和稳定剂,水为溶剂,用水热还原法合成了单质硒纳米棒。考察了反应时间、温度对产物形貌的影响。结果表明,制得单质硒纳米棒的最佳反应条件为:180℃下水热24 h,可以得到结晶良好、粒径均一、表面光滑的棒状纳米结构,直径约为5μm,长约为200μm。同时,探讨了单质硒纳米棒的生长机理。The selenium nanorods were prepared through hydrothermal method with seleninic acid as the source of Se and glucose as reducing agent and stabilizer,water as solvent.The effect of reaction time,temperature on the morphology of product was studied.The results showed that the optimal conditions were temperature 180 ℃,time 24 h.The structure of Se nanorod was diameter 5 μm,length 200 μm.The formation mechanism for selenium nanorod was discussed.
