摘要：
A ternary hybrid CdS/Pt-TiO2 nanotube (NT) photoelectrode was developed by dipping and deposition technique as well as successive ionic layer adsorption and reaction (SILAR). Small Pt nanoparticles (NPs) and CdS NPs were effectively deposited on both the inside and outside of the TiO2 NTs. The as-prepared hybrid shows enhanced photon absorption and photocurrent generation efficiency. Higher bactericidal effect to Escherichia colt was observed on the ternary hybrid CdS/Pt-TiO2 NTs as compared with Pt-TiO2 NTs or pure TiO2 NTs. (C) 2010 Elsevier Ltd. All rights reserved.
