摘要：

设计了一个参与科研型大学化学开放实验。该实验的主要内容包括：利用共沉淀法和电化学法制备前体水滑石，用离子交换法制备甲基橙插层水滑石以及利用IR、XRD、TEM、SEM、TG等手段表征材料结构。学生在掌握水滑石插层材料制备与表征方法的基础上，进一步自主设计实验方案，探究实验条件对插层材料结构的影响。

Abstract:

A college chemistry open experiment with students' participation in scientific research is developed in this paper. The experiment contents include the preparation of precursor by the co-precipitation process and the electrochemical method, the preparation of methyl orange intercalated hydrotalcite using the ion exchange method, and the structural characterization. The students design an experimental plan independently, and explore the influences of synthesis conditions to the structure of intercalated material, based on their mastering of preparation and characterization of materials.
