Physical modifications of single-walled carbon nanotubes (SWCNTs) with fullerodendrons, followed by complexation with RuCl₃ leads to the formation of CNT-photocatalysts that exhibit high quantum yields (QY = 12.8%) for the production of H₂ from water, even under illumination with NIR light (λ_irr = 1005 nm) in the presence of sacrificial donor. A Z-scheme photocatalytic system, consisting of such a CNT-photocatalyst, BiVO₄, and [Co(bpy)₃]^3+/2+ shows a production of H₂ (17 μmol/h) and O₂ (5.5μmol/h) under illumination from a solar simulator (AM-1.5) with a solar-to-hydrogen (STH) efficiency of 0.089%.
