Well-dispersed (below 1 nm) were deposited into the interlayer galleries of scrolled K4Nb6O17nanosheets. The unmodified nanoscrolls are good for UV light-driven hydrogen evolution from aqueous methanol solutions, and their activity can be significantly improved by anchoring a small amount (0.1 wt% Rh) of Rh(OH)3or Rh2O3 to the surface. The high hydrogen generation rate achieved in this system, 1480 µmol/h per 1g of , shows promise towards overall splitting using these catalytic composites.
