Plasmonic metal nanoparticles have been received increasing attention as visible-light-driven photocatalysts due to their unique optical property by localized surface plasmon resonance (LSPR). However, the electron transfer kinetics of photocatalytic reactions in the colloidal system is limited by the diffusion of the chemical moieties to the vicinity of photocatalysts. To achieve the high-efficiency photocatalysts, It would be a key point that the diffusion length of chemical species for photochemical reaction needs to be shortened. To do this, we designed a nanoscale reactor, in which the chemical species can be confined closely near the photocatalysts, through the surface engineering of nanoparticles and a type of additive. We examined the electron transfer kinetics between the free-standing colloidal nanoparticle system and the colloidal nanoreactor system. |
