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.

Latest U.S. Patent 9,945,040
This patent claims the use of ionomers containing cyclic amines for fuel cells and, CO? and water electrolyzers. We had previously shown that ionic liquids containing cyclic amines can be used to enhance electron transfer in CO? and water electrolyzers thus lowering the overpotential for CO? and alkaline water electrolysis. This patent shows that the cyclic amine can be in the form of … Read More

Latest Japanese Patent No. 6254565
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 CO? 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 showing that VBC groups can improve the stability of alkaline anion exchange membranes
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 CO? 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 Nov 27, 2017
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
