摘要
该文采用均相沉淀法制备了Ni(OH)_2纳米颗粒,运用X射线衍射技术和场发射扫描电镜对其结构和形貌进行表征,将其制作成电极,利用循环伏安和恒电流充放电技术对其电化学性质进行了研究。实践表明,因该实验涵盖的知识面广,有利于培养学生的科学素养和综合运用知识进行科学研究的能力,可以作为材料科学专业的综合性实验项目。
Ni（OH） 2 nanoparticles were prepared by homogeneous precipitation method. The morphology and structure were characterized by X- ray diffraction（XRD） and field emission scanning electron microscopy （FESEM）respectively. Further investigation on the electrochemical performance of Ni （OH）2 nanoparticles which used as the electrode materials was studied by cyclic voltammetry and constant current charge and discharge technology. The designing experiment includes a lot of knowledge and it is beneficial to develop students scientific literacy and comprehensive use of knowledge to carry out scientific research. Thus it can be applied as a comprehen- sive experimental of project in materials science.
