| Research Abstract |
We established the foundation of the In-situ/operando vibrational spectroscopy of water adsorbed on photocatalytic surfaces. The (0001) surfaces of α-Cr2O3(0001) was prepared as a surface of model catalyst. We succeeded in controlling the thickness of quasi-liquid water layer on CaF2 surfaces, which may open up a new technique to study photocatalytic reaction at gas/solid interface. Heterodyne-detected sum frequency generation spectroscopy for water adsorbed on solid surfaces was developed as a probe of photocatalytic process.
