Abstract Lanthanum carbonate nanoparticles were synthesized from the reaction of lanthanum acetate and Na2CO3 under sonication via sonochemical method. Lanthanum hydroxide nanoparticles were prepared by facial hydrothermal processing from the resulted product at 110 °C for 24 h. The role of surfactant, calcination temperature and sonication time were investigated on the morphology and particle size of the products. Products were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray photoelectron spectrum (XPS), and Fourier transform infrared (FT-IR) spectra. La2O3 nanoparticles were obtained by calcinations of the nanoparticles of lanthanum carbonate at 600 °C.

声化学法合成碳酸镧纳米粒子制备氢氧化镧和氧化镧纳米粒子

摘要 由醋酸镧与Na2CO3在超声处理下通过声化学法反应合成碳酸镧纳米颗粒。氢氧化镧纳米粒子通过面部水热处理从所得产物在 110°C 下制备 24 小时。考察了表面活性剂、煅烧温度和超声处理时间对产物形貌和粒径的影响。产品通过 X 射线衍射 (XRD)、扫描电子显微镜 (SEM)、透射电子显微镜 (TEM)、X 射线光电子能谱 (XPS) 和傅里叶变换红外 (FT-IR) 光谱进行表征。La2O3 纳米颗粒是通过在 600°C 下煅烧碳酸镧纳米颗粒而获得的。
