Nearhyphen;uv photon efficiency in a TiO2electrode: Application to hydrogen production from solar energy

摘要

Annhyphen;type (001) TiO2electrode irradiated at 365 nm was tested under anodic polarization: a saturation current independent of pH and proportional to light intensity has been observed. Accurate measurements of the incident power lead to a 60percnt; photon efficiency. A photoelectrochemical cell built with such an electrode, operated under solar irradiation without concentration, produced an electrolysis current of 0.7 mAthinsp;cmminus;2without applied voltage.
