Chinese Scientists Find New Way for Structural Analysis of Ionic Liquid
Scientists with Shanghai Institute of Applied Physics (SINAP), Chinese Academy of Sciences, used XAFS (X-ray absorption fine structure) technique to do structural analysis on ionic liquid ChCl−ZnCl2 in different ChCl:ZnCl2 ratios.
The research team, led by Xu Hongjie and Wu Guozhong, researchers of SINAP, investigated the components and structures of ionic liquid ChCl−ZnCl2 in different ChCl:ZnCl2 ratios by X-ray absorption fine structure spectroscopy, and established a new mechanism of interactions between Ch+ cation and Cl−Zn−Cl ion pairs or Cl−.
Ionic liquid, a special soft matter made of cation and anion, is considered a third liquid in the nature besides water and organic solvent. It has good electro-conductibility and thermo-stability and is widely used in organic synthesis, catalyze, electrochemistry, energy and material areas.
However, little research is carried out on the fine structural characters of ionic liquid due to lack of advanced methods. XAFS will make it possible for scientists to do more research on the analysis.
