Possibly scalable solar hydrogen generation with quasi-artificial leaf approach.

ABSTRACT: Any solar energy harvesting technology must provide a net positive energy balance, and artificial leaf concept provided a platform for solar water splitting (SWS) towards that. However, device stability, high photocurrent generation, and scalability are the major challenges. A wireless device based on quasi-artificial leaf concept (QuAL), comprising Au on porous TiO₂ electrode sensitized by PbS and CdS quantum dots (QD), was demonstrated to show sustainable solar hydrogen (490 ± 25 µmol/h (corresponds to 12 ml H₂ h^-1) from ~2 mg of photoanode material coated over 1 cm² area with aqueous hole (S^2-/SO₃^2-) scavenger. A linear extrapolation of the above results could lead to hydrogen production of 6 L/h.g over an area
