An aluminum electrode modified by a chemically deposited palladium pen-tacyanonitrosylferrate film was reported in [33]. Vitreous carbon electrode modified with cobalt phthalocyanine was used in [34]. Electrocatalytic activity of nanos-tructured polymeric tetraruthenated porphyrin film was studied in [35[. Codeposition of Pt nanoparticles and Fe(III) species on glassy-carbon electrode resulted in significant catalytic activity in nitrite oxidation [36[. It was shown that the photocatalytic oxidation at a TiO2/Ti film electrode can be electrochemically promoted [37].

The addition of a second oxide to the titania surface produces new nucleation sites for Au and improves the dispersion of the admetal. " In the CeO /TiOgCllO) systems, the Ce cations adopt a structural geometry (Fig. 6.2A) and an oxidation state (-1-3) which are quite different from those seen in bulk ceria or for ceria nanoparticles deposited on metal substrates. On TiO2(110), one has CegOg dimers that join forming wire-like structures on the terraces of the titania substrate. ... 

These wire-like structures contain sites which are very efifective for anchoring gold nanoparticles (see Fig. 6.2B). On CeO / TiOgCllO) surfaces, the dispersion of Au nanoparticles is substantially larger than seen on a pure TiO2(110) surface where Au mainly binds to the steps.
