| 摘 要： | 采用温和的水热-热解法, 在一定温度下, 通过调节Na2CO3溶液和可溶性钴盐的摩尔比控制产物的形貌, 得到具有一维结构的水热产物. 以该产物为前驱体制备了具有一维结构的Co3O4多晶. 以六次甲基四胺、尿素等代替Na2CO3溶液作为沉淀剂, 均得到了一维纳米结构的Co3O4, 表明CO2-3在水镁石CoO2层间的嵌入是得到一维结构水热产物的关键.

| Abstract: | The powders of one dimensional nanostructures of Co_3O_4 were synthesized hydrothermally followed by decomposition of the precursors in the Co(NO_3)_2-CO 2-_3 system. The aspect ratio of products could be controlled by tailoring the concentration of Co(NO_3)_2 aqueous solution. That urine and hexamethylenetetramine taking the place of sodium carbonate as the precipitants could also produce 1D Co_3O_4 showed lights on understanding the mechanism of formation of 1D structures. The existence of CO 2-_3 intercalated between the brucite layers played an important role in the formation of 1D structures. |
