Electrochemical devices comprising electro-catalyst mixtures include at least one Catalytically Active Element and, as a separate constituent, one Helper Catalyst. The electrocatalysts can be used to increase the rate, modify the selectivity or lower the overpotential of chemical reactions. These electrocatalysts are useful for a variety of chemical reactions including, in particular, the electrochemical conversion of CO2.
Dioxide Materials was awarded a $720,000 subcontract under an ARPA-E project “NOVEL SCALABLE MEMBRANE DESIGNED FOR ENERGY EFFICIENT ELECTROCHEMICAL CONVERSION OF CO2 INTO USEFUL PRODUCTS”
This patent shows that while tetramethylimidazole (TMIM) degrades at 60 degrees C in 1M KOH, the TMIM ligand in our Sustainion® polymers is stable under the same conditions.

This patent claims the use of ionomers containing cyclic amines for fuel cells and, CO₂ and water electrolyzers. We had previously shown that ionic liquids containing cyclic amines can be used to enhance electron transfer in CO₂ and water electrolyzers thus lowering the overpotential for CO₂ and alkaline water electrolysis. This patent shows that the cyclic amine can be in the form of … Read More

Our latest Japanese Patent No. 6254565 provides further evidence that the combination of a metal and an imidazolium gives lower overpotentials than the metal alone. This discovery has enabled us to reach high currents in water and CO₂ electrolyzers, which paves the way to more cost-effective routes to sustainable chemicals and fuels production.
Patent US9,845,450 issued on Dec 26, 2017. The patent is a continuation of our efforts to demonstrate that tetramethylimidazolium (TMI) functionalized styrene alkaline anion exchange membranes are useful for alkaline water and alkaline CO₂ electrolysis. This patent shows the importance of having extra vinylbenzyl chloride (VBC) units in the polymer to promote stability. TMI, itself is not stable in alkaline … Read More
Patent US9,790,161 issued on Nov 27 2017. Italso issued recently in China on Dec 3, 2017 as CN105339336. This patent provides a new route to the production of acrylic acid from CO2 and acetylene. First the CO2 is electrolyzed to produce formic acid. Then the formic acid reacts, via a number of intermediates to form acrylic acid. There are two unique parts … Read More
