    • PURPOSE: An alkali-CoO2 based compound and an exfoliation method thereof are provided to embody two dimensional nano-structure using a nano-sheet by intercalation of the chemical product. CONSTITUTION: An exfoliation method of an alkali-CoO2 based compound comprises the following steps: oxidizing the alkali-CoO2 based compound and intercalating the oxidized alkali -CoO2 based compound by adding amine based compound. The oxidation of the alkali -CoO2 based compound is processed by chemical oxidation and uses one selected from persulfate solution, hydrogen peroxide(H2O2), and hyper sodium chlorite(NaClO). A molar ratio of the one which is selected from persulfate solution, hydrogen peroxide(H2O2), and hyper sodium chlorite(NaClO) to the alkali -CoO2 based compound is1:1-10:1.
    • 目的:提供碱-CoO 2基化合物及其剥离方法,以通过插入化学产品纳米片体现二维纳米结构。 构成:碱金属氧化物基化合物的剥离方法包括以下步骤:通过加入胺基化合物氧化碱-CoO 2基化合物并插入氧化的碱性-CoO 2基化合物。 通过化学氧化处理碱性-CoO 2基化合物的氧化,并使用选自过硫酸盐溶液,过氧化氢(H 2 O 2)和高亚氯酸钠(NaClO)的一种。 选自过硫酸盐溶液,过氧化氢(H2O2)和高亚氯酸钠(NaClO)与碱性-CO 2 O 2化合物的摩尔比为1:1-10:1。
