Study on the Preparation and Florescence of Cinnamate-pillared Hydrotalcite

Shuhua Qi

Abstract

Zn/Al hydrotalcite(Zn/Al-LDHs) were prepared by the nucleation/crystallization in this thesis.The cinnamate-pillared hydrotalcites of Zn/Al-LDHs have been successfully assembled by returns mixes precipitation method and original place method in ethylene glycol.The samples were characterized by FTIR and means of fluorescence spectroscopy.The results showed that cinnamic acid radical can be substituted hydrotalcite,zinc and aluminum precursors hydrotalcite interlayer CO32-,are well-structured assembly of cinnamic acid hydrotalcites,cinnamic acid hydrotalcites has good absorption between 300～400nm,so it has good fluorescence properties.
