Quantum-Dot-Sensitized TiO2 Inverse Opals for Photoelectrochemical Hydrogen Generation

Quantum-Dot-Sensitized TiO2 Inverse Opals for Photoelectrochemical Hydrogen Generation

A new nanoarchitecture photoelectrode design comprising CdS quantum‐dot‐sensitized, optically and electrically active TiO2 inverse opals is developed for photoelectrochemical water splitting. The photoelectrochemical performance shows high photocurrent density (4.84 mA cm−2 at 0 V vs. Ag/AgCl) under...

Zusammenfassung:A new nanoarchitecture photoelectrode design comprising CdS quantum‐dot‐sensitized, optically and electrically active TiO2 inverse opals is developed for photoelectrochemical water splitting. The photoelectrochemical performance shows high photocurrent density (4.84 mA cm−2 at 0 V vs. Ag/AgCl) under simulated solar‐light illumination.
