Photoelectrochemical oxidation of organic substances and electricity generation in the presence of nanocrystalline titania photocatalyst.
A chemically biased, two compartment cell has been used to photoelectrochemically degrade several substances and produce electricity. The photoanode of the cell was made of nanocrystalline Titania deposited on a conductive transparent fluorine-doped tin oxide electrode. The dark cathode was made of an identical electrode as the photoanode with Pt nanoparticles deposited on the nanocrystalline Titania film. The photoanode was activated by UVA radiation emitted by Black-light tubes or directly by natural (Solar) light. Photo-oxidation of several substances produced electricity. Efficiency calculations have been made in all studied cases.
