A NEW CELL FOR THE COLLECTION OF COMBINED EXAFS XRD DATA IN-SITU DURING SOLID/LIQUID CATALYTIC REACTIONS/

A new experimental reaction cell which enables the recording of combin ed EXAFS/XRD data over a wide range of temperatures of a solid that ca talyses liquid reactions in the liquid state has been designed and con structed. The cell is particularly suitable for the in situ study of b oth short-range and long-range structural changes during solid/liquid heterogeneous catalytic reactions. It is also suitable for the study o f intercalation phenomena and may be readily adapted for certain types of electrochemical investigations. The use of this cell is exemplifie d by the oxidation of cyclohexene over a Zn(II)Al(III)-hydrotalcite co ntaining intercalated cobalt phthalocyaninetetrasulphonate anions.
