| Outline of Final Research Achievements |
Many efforts have been devoted to synthesis of photocatalysts that respond to visible light. In previous study, Au nanoparticles supported on metal oxide have been applied as a new type of photocatalysts responding to visible light. we found that action spectra in photocatalytic reactions over Au/metal oxide were in good agreement with their absorption spectra, which suggested that photocatalytic reactions were induced by photoabsorption due to surface plasmon resonance (SPR) of the supported Au nanoparticles. In this study, we examined control of absorption due to SPR by modification of Au nanoparticles supported on metal oxide with Ag and Cu. These samples were active for mineralization of formic acid and selective oxidation of alcohols to carbonyl compounds under visible-light irradiation and exhibited the best performance when irradiated by light overlapping with their SPR.
