Noble metal nanoparticles have been received increasing attention as visible light-driven photocatalysts due to unique optical properties arising from localized surface plasmon resonance, and catalytic activity in the nanoscale regime. However, these types of photocatalysts have inherent limitations in that the rate of recombination of excited electrons and holes is too fast, so charge carriers cannot sufficiently participate in a chemical reaction. To enhance reaction rate in plasmonic photocatalysts, it can be key ideas that either the migration length of excited electrons or diffusion length of chemical substances needs to be shortened. In this study, we made a confided-nanospace that can reduce the distance between photocatalysts and chemical substances through surface engineering on nanoclusters. We will compare the reaction kinetics between the freestanding nanoparticle and the nanospace system. |
