View the Complete Application at the US Patent & Trademark Office
Electrodes useful in dye sensitized photoelectrosynthesis cells provide a coreshell nanoparticle having a chromophore and a catalyst, or a chromophore-catalyst assembly, linked to the shell material. Optionally, an overlayer stabilizes the chromophore or chromophore-catalyst assembly on the shell material. In some embodiments, the core material comprises tin oxide; the shell material comprises titanium dioxide; the chromophore-catalyst assembly includes [(PO.sub.3H.sub.2).sub.2bpy).sub.2Ru(4-Mebpy-4'-bimpy)Ru(tpy) (OH.sub.2)].sup.4+, and the overlayer comprises aluminum oxide or titanium dioxide.
