Abstract:

In2O3/ZnO/fluorine-doped tin oxide (FTO) photoanode was prepared by electrochemical anodization-hydrothermal approach and to assemble a visible light activated photocatalytic fuel cell (PFC) with CuO/Cu cathode. The as-fabricated electrodes were scrutinized using field-emission scanning electron microscopy (FESEM), energy dispersive X-ray (EDX) and electrochemical impedance spectroscopy (EIS) analyses. The maximum power density and chlortetracycline hydrochloride (CTCH)-bearing aquaculture wastewater removal efficiency of In2O3/ZnO/FTO PFC treatment for 240 min were 0.3084 µW cm-2 and 91.5%, respectively, which were much higher than that of PFC with ZnO/FTO photoanode (0.1805 µW cm-2 and 67.5%, respectively). The spectacular performance of this PFC system was realized by the S-scheme heterojunction of the photoanode between In2O3 and ZnO/FTO, which boosted the segregation of photoexcited carriers and yielded powerful active radical species for the photoelectrocatalytic activity. This study can serve as reference for the devise and heterojunction establishment of highly effective electrodes of PFC with visible light response.
