Electrochemical Deposition (ECD) of ZnO as the Photoanode in Dual‐Chamber Photocatalytic Fuel Cell (PFC) for Methyl Red Degradation

Abstract Photocatalytic fuel cell (PFC) is known to treat the organic‐based wastewater efficiently. The coating method of zinc(II) oxide (ZnO) as photocatalyst on zinc (Zn) plate photoanode plays important role in maintaining efficiency and power generation from PFC. In present study, a new ZnO developed by using electrochemical deposition (ECD) removal well are compared with typical ultrasonicate method. A dual‐chamber PFC constructed ZnO/Zn graphite cathode methyl red dye synthetic wastewater. surface morphology both methods observed scanning electron microscope (SEM) before after treatments. dual chamber ECD shows faster complete degradation rate higher than Although, can reach 100% dye, maximum output for 134.67 mW cm −2 while 285.30 under optimum conditions.
