Abstract

A custom-tailored single-walled carbon nanotube (SWCNT) photocatalyst with an electron-extracting TiO_x shell, i.e., a SWCNT/fullerodendron/TiO_x coaxial nanowire, has been fabricated. Due to the presence of the TiO_x shell, the SWCNT/fullerodendron/TiO_x coaxial nanowire shows an enhanced photocatalytic activity (Φ = 0.47) for the evolution of hydrogen from water under irradiation with visible light (λ = 450 nm).
