Platinum and Iridium Oxide Co-modified TiO(2) Nanotubes Array Based Photoelectrochemical Sensors for Glutathione

Oriented TiO(2) nanotubes, which are fabricated by anodic oxidation method, are prospective in photoelectrochemical analysis and sensors. In this work, Pt and IrO(2) co-modified TiO(2) nanotubes array was prepared via a two-step deposition process involving the photoreductive deposition of Pt and ch...

description Oriented TiO(2) nanotubes, which are fabricated by anodic oxidation method, are prospective in photoelectrochemical analysis and sensors. In this work, Pt and IrO(2) co-modified TiO(2) nanotubes array was prepared via a two-step deposition process involving the photoreductive deposition of Pt and chemical deposition of IrO(2) on the oriented TiO(2) nanotubes. Due to the improved separation of photo-generated electrons and holes, Pt-IrO(2) co-modified TiO(2) nanotubes presented significantly higher PEC activity than pure TiO(2) nanotubes or mono-modified TiO(2) nanotubes. The PEC sensitivity of Pt-IrO(2) co-modified TiO(2) nanotubes for glutathione was also monitored and good sensitivity was observed.
