Behavior of bromide in the photoelectrocatalytic process and bromine generation using nanoporous titanium dioxide thin-film electrodes
In this study, the photoelectrocatalytic behavior of bromide and generation of bromine using TiO 2 was investigated in the separate anode and cathode reaction chambers. Our results show that the generation of bromine begins around a flatband potential of −0.34 V vs. standard calomel electrode (SCE)...

Summary: | In this study, the photoelectrocatalytic behavior of bromide and generation of bromine using TiO
2 was investigated in the separate anode and cathode reaction chambers. Our results show that the generation of bromine begins around a flatband potential of −0.34 V vs. standard calomel electrode (SCE) at pH 3.0 under UV illumination and increases with an increase in positive potential, finally reaching a steady-state concentration at 1.0 V vs. SCE. Maximum bromine formation occurs over the range of pH 4–6, decreasing sharply at conditions where the pH
