Oxygen Catalysts

Oxygen catalysts for Fuel cells and Hydrogen Peroxide Generation.

The oxygen flux agents referred to above in item 4 bear considerable resemblance to porphyrin catalysts used in oxygen electrodes. It has already been noted that several of the materials are capable of generation of hydrogen peroxide without obvious degradation on a short time-scale. Alteration of the catalyst structures lead to different rates and strengths of oxygen binding and a proper fundamental study of these effects would provide improved catalysts. It is envisioned that the hydrogen peroxide function could be incorporated in to an SPE cell with a lead dioxide/Ebonex anode for ozone generator to provide a potent on-site system for combined peroxide and ozone generation for water treatment, sterilization and institutional laundry use, among many other uses. Both this application and fuel cell catalysts involve membrane-catalyst combinations similar to that already under development for Co-factor regeneration and would extend possible applications for our capabilities.
