A step-wise structural ZnSe/CdS co-sensitized TiO2 nanotube (NT) electrode was prepared by pulse-electrodeposition and successive ionic layer adsorption and reaction (SILAR), with an aim towards enhancing the absorption efficiency of TiO2 NTs in visible light region and enhancing the photo-electrical transform efficiency. The as-prepared CdS/ZnSe/TiO2 NTs were applied to the photoelectrocatalytic inactivation of E. coli. A complete inactivation of 3.0 × 108 cfu mL−1 E. coli was observed after 60 min of photoelectrocatalysis process under the illumination of visble light.
