Photoanode in photocatalytic fuel cell (PFC) plays an important role in the dual chamber PFC integrating electro-Fenton (EF) hybrid system (PFC-EF system) since the photo-excitation process on the photoanode will contribute to the electrons for electricity generation and electro-generation of hydrogen peroxide in EF process. Fabrication of different types of photoanodes were carried out by using anodizing and immobilization method, respectively. The fabrication methods significantly affected the efficiencies of photoanodes in the Amaranth treatment. The characterization of the fabricated photoanodes was carried out by X-ray diffraction and scanning electron microscopy. The immobilized ZnO/Zn photoanode achieved the highest degradation efficiencies in both PFC (80.36%) and EF (86.88%). The immobilized ZnO/Zn photoanode also contributed to the highest power density (4.545 μW cm-2).
