The TiO2 nanotube arrays (TiO2 NTs) sensitized by Ag-AgBr nanoparticles were prepared with different alkali (sodium hydroxide, urea and methenamine) as mineralizers by a hydrothermal method, and the TiO2 NTs/Ag-AgBr photoelectrode showed high visible light absorption, transient photocurrent and photoelectrocatalytic (PEC) performances. The results indicated that TiO2 NTs/Ag-AgBr (SH) photoelectrode showed the high visible light photocurrent density of 5.86 mA/cm(2), photovoltage of -0.31 V/cm(2) and PEC removal efficiency for MO (71.97%), RhB (59.88%), MB (80.76%) and Cr(VI) (52.24%), respectively. The high PEC property could be attributed to the high activities of solar absorption and electron separation. The excellent photoelectrochemical property of TiO2 NTs/Ag-AgBr would induce the novel photoelectrode promising applications in solar cells and wastewater treatment.
