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 H-2 from water, even under illumination with NIR light (lambda(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 H-2 (17 mu mol/h) and O-2 (5.5 mu mol/h) under illumination from a solar simulator (AM-1.5) with a solar-to-hydrogen (STH) efficiency of 0.089%.
