Ti/TiO2/Cu2O based electrodes as photocatalysts in PEC cells
Composite Ti/TiO2/Cu2O electrodes were produced by electrodeposition of p-Cu2O nanoparticles over the surface of TiO2 nanotubes generated by one-step electrochemical anodization of titanium. The effect of electrodeposition potential and duration of the electrodeposition experiments on size and morphology of the Cu2O nanoparticles was evaluated by FE-SEM analysis. In order to evaluate the photo-catalytic activity of the composite electrodes, photo-degradation experiments with methylene blue and photo-electrochemical tests were performed.
