Enhanced Electrocatalytic Water Splitting for Green Hydrogen Generation

Case ID:

A new metallopolymer catalyst has been developed to improve and simplify water electrolysis, targeting energy storage from renewable power production. Initial studies have shown that these metallopolymers have high turn-over frequency and improved stability in aqueous systems for producing hydrogen.


Platinum and other catalytic materials have been commercially used or experimentally tested as cathodes for hydrogen production. This catalyst has been developed as a mimic of a biological catalyst for hydrogen reduction. Increased demand for hydrogen, use of hydrogen as a non-carbon fuel source, and interest in enabling electrochemical processes for energy storage or enhanced utilization from renewable power drive the need for catalysts with improved performance.
