| Abstract: | It was found that photoelectrochemical water oxidation takes place at a polynuclear iron-cyanide complex-coated electrode called Berlin Brown (BB; Fe4IIIFeIII(CN)6]33 3X). The electrode-coated BB showed electrocatalytic activity for water oxidation to produce O2 not only in the dark but also under illumination to result in photoinduced water oxidation. The amount of the photoelectrochemically produced O2 increased with the thickness of the BB film, indicating that the BB works as a bulk catalyst. |
