Chalcogenide material as high photoelectrochemical performance Se doped TiO2/Ti electrode: Its application for Rhodamine B degradation

Abstract

Abstract The objective of this research to synthesize the Selenium (Se) doped TiO2/Ti electrode as a novel chalcogenide material by anodizing and dip-coating method. The electrode was applied for Rhodamine B (RhB) degradation test in high-photoelectrochatalytic (PEC) performance. It is found out that the morphology and element containing on Se-TiO2/Ti electrode has honeycomb structure with the element composition of Ti (51.09%), O (36.91%), and Se (12.00%), respectively. In addition, the PEC response test using Linear Sweep Voltammetry (LSV) showed that the optical properties of Se-TiO2/Ti electrode was active under visible light, meanwhile the TiO2/Ti was active under ultraviolet (UV) light. The PEC test using Multi Pulse Amperometry (MPA) technique was exhibited that the 5 ppm RhB corresponded to the degradation of 73.27%.
