Preparation and properties of mesoporous TiO₂ electrode sensitized by xanthophyll

Mesoporous TiO₂ electrode material was prepared by EISA (evaporation induced self-assembling) and then it was coated on the surface of ITO conductive glass and sensitized by adsorbing xanthophylls after calcining. The investigating about photoelectrochemical properties shows that this mesoporous TiO₂ electrode sensitized by xanthophyll possesses high photoelectochemical activity with a open-circuit photovoltage of 594 mV, though the xanthophyll doesn't have photoelectrochemical activity in plant.
