模式识别在核壳结构钴铝复合氢氧化物形貌可控合成中的应用
|
摘要
通过正交试验设计,使用溶剂热法制备了一系列钴铝复合氢氧化物。运用我们实验室自主开发的软件,对实验数据结果进行最佳投影识别,找出了形成核壳结构钴铝复合氢氧化物的边界条件。采用逆投影法设计了新样本,新样本的实验结果与预测结果一致。因此,所建模式识别模型对于核壳结构钴铝复合氢氧化物形貌的可控合成是非常有用的,为其它材料的可控合成提供了参考方法。
With the orthogonal experimental design, a series of Co-Al hydroxides have been prepared by using solvothermal method. The optimal projection recognition(OPR) developed in our lab has been used to find the regularities of forming core-shell Co-Al hydroxides superstructures. The new samples predicted to be core-shell Co-Al hydroxides superstructures were designed by using the inverse projection based on the OPR method. The predicted results agreed well with our experiments. Therefore, the work presented is very useful in the shape-controlled synthesis of core-shell Co-Al hydroxides superstructures, providing a reference method for the controlled synthesis of other materials.
