Multielectrode photoelectrochemical cell for unassisted photocatalysis and photosynthesis

摘要

A multielectrode photoelectrochemical cell in which at least contains two bipolar electrode panels for photoelectrochemical reactions such as water photolysis to produce H2 O2 without external bias. In one embodiment of the present invention, a bipolar TiO2/Pt multielectrode photoelectrochemical cell was fabricated with five panels in series. The cell permitted unassisted photolytic (Xe lamp) water splitting to produce H2 and O2 with H2O2 molar ratio of 2.4/1.
