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.

Key words: Open chemical experiment, Hydrotalcite, Intercalated materials, Structural characterization, Practical teaching
