Electrolytic and anticorrosion coatings

Water electrolysis is a cornerstone of renewable energy storage technology, but still requires a strong value proposition to become widespread and economically viable. Our electrolysis systems, enabled by the development of highly selective catalysts, simultaneously treat organic wastewater and generate renewable fuel. They oxidize contaminants in wastewater selectively, preventing anode dissolution and without changing the water itself - similar to the way a catalytic converter removes harmful contaminants in the air. 

Current state-of-the-art processes to treat organic wastewater are multi-step, unstable, energy-intensive, and costly, while our method is additive-free, efficient, and employs selective catalysts on the surface of a stationary electrode. Proof-of-concept experiments for these reactions have been successful, prototypes have been built, and functioning lab-scale electrolyzer stacks are in use.

Our technology is enabled by recently-discovered surface-bound molecular

coatings, a new type of material that enables oxidation chemistry with  

minimal use of materials. Integrated into a polymer electrolyte membrane

electrolyzer, these coatings are able to oxidize dilute organic contaminants.

These materials are also useful as anticorrosion coatings on anodes in the 

elecrochemical industry. Contact us for more information on these applications.
