Abstract: The reduced graphene oxide (rGO) doped and Ag-TiO2 based photoelectrodes were prepared to study the effect of the composite method on the electron transport and tetracycline degradation by photocatalyst. The electrodes were characterized by electrochemical impedance spectroscopy and Mott-Schottky curve. The results showed that the interface resistance of the double-layer/thin film was reduced by the layered composite method on the surface of the carrier; while the total charge transfer resistance was mainly reduced by the fully mixed composite method. In addition, the concentration of the electron donor increased with the increasing of composite amount. When the rGO mass fraction was 0.45% and 0.25%, the degradation rate of tetracycline by the layered composite and the fully mixed doped electrode was 11.4% and 2.3% higher than that of Ag-TiO2, respectively. Under the applied 0.5 V bias voltage, the LG6 degradation efficiency of the layered composite electrode was increased by 5.3%; while the MG2 efficiency of the fully mixed composite electrode was not improved. The layered composite method can improve the electron transport efficiency more effectively on the surface of photocatalyst.
