| Outline of Final Research Achievements |
To improve the activity and selectivity of catalysis, direct observation of reaction processes by spectroscopic methods is important. In the present study, in situ observations of catalytic reactions were carried out by using soft X-ray absorption spectroscopy of liquid in transmission mode, which has been recently established. Although cross coupling reaction, the original target of in-situ observation, has not been able to be investigated, the analysis of reaction kinetics for the cyanopyrazine hydration on titanium oxide catalyst has successfully observed.
In addition, aqueous crown ether inclusion complexes were also measured as the investigation of interaction between organic compounds and ions, which is important for catalyses, by soft X-ray absorption spectroscopy. As a result, local structures of the crown ether inclusion complexes have been clarified.
