Open the CIPO recordAbstract From the Canadian patent
Photochemical diodes are provided which use light to drive both endoergic and exoergic chemical reactions such that optical energy is converted into chemical energy. The photochemical diodes are typically suspended in a bulk volume matrix of the constituant chemical reactants. The photochemical diodes in the form of either Schottky-type diodes or p-n type diodes are employed, for example, to convert water into hydrogen plus oxygen (or hydrogen peroxide); to convert hydrogen sulfide into hydrogen plus sulfur; and to photo-catalyze chemical reactions. The photochemical diodes of the invention comprises two portions a first portion comprising an appropriately doped semiconductor material of a …
