AbstractComposite PEDOT films, prepared using vapour phase polymerisation incorporating with nanoparticulate Ni (‘nano-Ni’) on FTO glass have been studied as photoelectrocatalysts of water oxidation in 0.2 M Na2SO4 electrolyte at different pH. The PEDOT/nano-Ni Films proved to be active at high pH generating current densities at 0.80 V (vs Ag/AgCl) of 0.655 mA/cm2 (including a photocurrent of 0.4 mA/cm2) under light illumination of 0.25 Sun. A variety of techniques were used to study and characterized the films, including: cyclic voltammetry, chronoamperograms, gas chromatography and scanning electron microscope.
