| Research Abstract |
We have developed a near ambient-pressure x-ray photoelectron spectroscopy system with which we can measure photoelectron spectra for adsorbed species as well as sample surfaces under near ambient pressure conditions. We applied this technique to real-time tracing of dynamic processes such as formation reactions of photocatalyst surfaces and catalytic reactions at solid surfaces. The application of this technique enabled us to detect several surface reaction processes that have never been observed. Based on the obsrvations, we successfully gained deeper insight into the mechanisms of the surface reactions.
