| 摘 要： | 以乙酸钴为钴源,水合肼为还原剂,在不同表面活性剂下,溶剂热法制备出不同形貌的二维、三维钴微纳米颗粒。通过扫描电子显微镜（SEM）、X射线能量色散谱（EDS）和X射线衍射（XRD）对产物进行了表征。采用自制的2-十一烷基-1-二硫脲乙基咪唑啉季铵盐（SUDEI）为表面活性剂时,制备出直径400～600nm,厚度约100nm的六角盘状二维产物,采用其他表面活性剂只能制备出三维的花状钴。初步探讨了溶剂热条件下钴微纳米颗粒的构筑习性。

| Abstract: | Using cobalt acetate hexahydrate as cobalt source and hydrazine hydrate as reducing agent,the two/three dimension cobalt micro/nanoparticles of different morphology were synthesized by solvothermal method in different surfactants.The products were characterized by scanning electron microscope（SEM）,energy dispersive spectrometer（EDS）and X-ray diffraction（XRD）.The two-dimension Co hexagonal nanoplatelets,diameter about 400-600nm,thickniss 100nm,were successfully synthesized when using 2-undecyl-1-dithioureido-ethyl-imidazoline（SUDEI）as surfactant,while using other surfactants obtained three-dimension flower-like cobalt.The possible growth mechanism of cobalt micro/nanoparticle in the condition of solvothermal was investigated as well. |
