摘要:

以氯化胆碱/尿素低共熔溶剂为介质通过恒电位沉积法成功制备了形状和尺寸均一的橄榄状镧粒子. 采用扫描电子显微镜(SEM)、透射电子显微镜(TEM)、X射线能量色散谱(EDX)和X射线光电子能谱(XPS)等技术对所制备的样品进行表征. 同时,研究了沉积电位、温度和时间等因素对样品尺寸、形貌的影响,确定恒电位法制备橄榄状镧粒子的优化工艺条件为沉积电位-1.7 V、温度80 oC和沉积时间15 min.

Abstract:

With the choline chloride/urea deep eutectic solvents (DESs) as the medium, the olive-like lanthanum particles with uniform shape and size were successfully prepared through a potentiostatic deposition method. The prepared samples were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy dispersive X-ray (EDX) spectroscopy and X-ray photoelectron spectroscopy (XPS). At the same time, the effect of deposition potential, temperature and time on the size and morphology of samples was investigated. The results demonstrated that the optimum conditions for the preparation of olive-like lanthanum particles were as follows: deposition potential of -1.7 V, temperature of 80 oC and deposition time of 15 min.

Key words: deep eutectic solvents, lanthanum, electrodeposition
