摘要
以硝酸钴为原料,柠檬酸三钠为模板,六次甲基四胺为成沉淀剂水热制备了核壳结构Co3O4,X射线衍射(XRD)、扫描电镜(SEM)测试表明,柠檬酸三钠的加入使制备的Co3O4呈现核壳状结构,循环伏安等电化学研究表明该材料的电化学电容性能较好,单电极比电容达到333 F/g。
The core-shell structured Co3O4 was synthesized by hydrothermal method with cobaltous nitrate [Co(NO3)3] and hexamethylenetetramine(C6H12N4) as raw materials,and sodium citrate(C6H5Na3O7) as template.The XRD(X-ray diffraction) and SEM(scan electron microscope) results show that the prepared Co3O4 has the core-shell structure due to the addition of C6H5Na3O7.The electrochemical tests show that the material has a good capacitance,and the specific capacitance of single electrode is up to 333 F/g.
