Abstract:
A ternary hybrid CdS/Pt-TiO(2) 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 TiO(2) NTs. The as-prepared hybrid shows enhanced photon absorption and photocurrent generation efficiency. Higher bactericidal effect to Escherichia coli was observed on the ternary hybrid CdS/Pt-TiO(2) NTs as compared with Pt-TiO(2) NTs or pure TiO(2) NTs.
