Abstract

An anodic WO3-loaded on hexagonal rod-like ZnO/Zn (WO3/ZnO/Zn) with the Z-scheme structure was first developed and employed in a sunlight-powered photocatalytic fuel cell (PFC). Both the COD removal and photoelectric performance of sunset yellow (SSY) has been systematically tested under sunlight irradiation. The COD removal of SSY in the WO3/ZnO/Zn PFC was 84.6% over 240 min period. The maximum power density (Pmax) of the WO3/ZnO/Zn PFC was 0.1052 µW cm-2, which was 1.86 times that of the pure ZnO/Zn PFC in degrading SSY compounds. The enhanced Z-scheme WO3/ZnO/Zn PFC could be ascribed to improved electron transfer via the hexagonal rod-like structure and efficient charge separation and thereby maintained high redox ability for photoelectrochemical activity. The WO3/ZnO/Zn PFC performance had also investigated in treating real food wastewater, 63.6% COD was removed and generated 0.498 µW cm-2 Pmax output.
