Latest Patents

Hyoungjeen Jeen holds a patent for a "Strontium cobaltite oxygen sponge catalyst and methods of use." This invention allows for rapid, reversible redox activity at significantly reduced temperatures, as low as about 200°C. The catalyst is based on epitaxially stabilized, oxygen vacancy ordered SrCoO and thermodynamically unfavorable perovskite SrCoO. The fast, low-temperature redox activity in SrCoO is attributed to a small Gibbs free energy difference between the two topotactic phases. Epitaxially stabilized thin films of strontium cobaltite provide a catalyst that can rapidly transition between oxidation states at substantially low temperatures. The patent also describes methods for transitioning a strontium cobaltite catalyst from a first oxidation state to a second oxidation state.
