对了，我的碳酸根插层离子用得比较少，是根据金属离子的量，按水滑石的公式计算的，可能刚刚够，或者过量一点点，不知道这个是否有影响～求各位大神指教

In a typical procedure, calculated amount of Co(NO3)2·6H2O (10–40 mmol), Al(NO3)3·9H2O (10 mmol), (AR, Sinopharm Chemical Reagent Co. Ltd., China) were dissolved together in 200 mL deionized water. This mixed solution is referred to as solution A. Solution B was a 100 mL mixture of 25 mmol Na2CO3 and 80 mmol NaOH (AR, Sinopharm Chemical Reagent Co. Ltd., China) with concentrations of 0.25 and 0.8 mol/L. Solutions A and B were simultaneously added dropwise into a glass reactor under vigorous stirring at room temperature and the pH value of solution was kept at 8.5.

变成氧化铜了，温度太高了

我也做过这个，出现了相同的情况，但是xrd后也出现了完整的水滑石结构
