Abstract:
Dye-encapsulated single-walled carbon nanotubes (SWCNTs) were employed for the construction of a coaxial three-component dye/SWCNT/C₆₀ heterojunction. Despite the larger diameter (∼1.4 nm) of the SWCNTs relative to that set by Flavel’s rule (0.95 nm), the photoinduced electron transfer from dye-encapsulated SWCNTs to C₆₀ proceeded smoothly, resulting in the photosensitized evolution of H₂ from H₂O using a ferrocenyl-based photosensitizer, which was confirmed by the action spectra.
