| Outline of Final Research Achievements |
In this study it was aimed to develop spectroscopic operando observation systems using soft-X-rays and infrared rays and to apply these techniques to detection of catalytically active phases and reactants adsorbing on the active phases under reaction conditions. The development of both operando observation systems has been successfully achieved, which enables us to observe catalytically active surfaces under reaction conditions via X-ray photoelectron spectroscopy, polarized X-ray absorption spectroscopy and polarization-modulation infrared reflection absorption spectroscopy, combined with monitoring of catalytic activity by mass spectrometry. On the basis of this approach we have been able to reveal catalytically active phases and reaction mechanisms, which had been hardly uncovered, and thus we could demonstrate that this approach is useful in catalytic studies.
