A US Patent (Patent No.: 9,985,296) entitled "Polymer-Derived Catalysts and Methods of Use Thereof" was recently issued to Professor Tewodros (Teddy) Asefa and his former PhD student, Dr. Rafael Silva. The patent is on novel synthetic methods involving self-assembly, polymerization and pyrolysis to convert polymer/silica nanocomposite materials, such as polyaniline/mesoporous silica, into nanoporous heteroatom-doped carbons and demonstration of the ability of the products to serve as efficient metal-free electrocatalysts for reactions on electrodes in fuel cells and water electrolyzers. Such materials have the potential to replace precious noble metal catalysts, such as platinum, iridium, rhodium, etc., that are widely used in fuel cells, electrolyzers and other catalytic processes but are unsustainable for large-scale applications.
