Outline of Final Research Achievements

The purpose of this study is revealing fundamental issues in photocatalysts for the water splitting reaction driven by solar light. Two research topics were examined; (1) electronic excited states of TiO2 photocatalysts observed with resonant Raman scattering and (2) electron-hole recombination kinetics in NaTaO3 photocatalysts doped with strontium.
