Photosensitization of nanocrystalline TiO2 films by pomegranate pigments with unusually high efficiency in aqueous medium
Abstract
An aqueous system based on a TiO2 layer photosensitized by natural pigment(s) from pomegranate, shows relatively high stability under illumination with a quantum yield of 0.74 and a photovoltage of 0.46 V.
