A donor-chromophore-catalyst assembly for solar CO₂ reduction.

ABSTRACT: We describe here the preparation and characterization of a photocathode assembly for CO₂ reduction to CO in 0.1 M LiClO₄ acetonitrile. The assembly was formed on 1.0 μm thick mesoporous films of NiO using a layer-by-layer procedure based on Zr(iv)-phosphonate bridging units. The structure of the Zr(iv) bridged assembly, abbreviated as NiO|-DA-RuCP₂ ²⁺-Re(i), where DA is the dianiline-based electron donor (N,N,N',N'-((CH₂)₃PO₃H₂)₄-4,4'-dianiline), RuCP²⁺ is the light absorber [Ru((4,4'-(PO₃H₂CH₂)₂-2,2'-bipyridine)(2,2'-bipyridine))₂]²⁺, and Re(i) is the CO₂ reduction catalyst, Re
