Abstract:

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 [(POH)bpy)Ru(4-Mebpy-4′-bimpy)Ru(tpy) (OH)], and the overlayer comprises aluminum oxide or titanium dioxide.
