New Chalcogens Findings Has Been Reported by Investigators at Technical University of Denmark (Hollow Spheres of Iron Carbide Nanoparticles Encased in Graphitic Layers as Oxygen Reduction Catalysts)

By a News Reporter-Staff News Editor at Life Science Weekly -- Investigators discuss new findings in Chalcogens. According to news originating from Roskilde, Denmark, by NewsRx correspondents, research stated, "Nonprecious metal catalysts for the oxygen reduction reaction are the ultimate materials and the foremost subject for low-temperature fuel cells. A novel type of catalysts prepared by high-pressure pyrolysis is reported."

Our news journalists obtained a quote from the research from the Technical University of Denmark, "The catalyst is featured by hollow spherical morphologies consisting of uniform iron carbide (Fe3C) nanoparticles encased by graphitic layers, with little surface nitrogen or metallic functionalities. In acidic media the outer graphitic layers stabilize the carbide nanoparticles without depriving them of their catalytic activity towards the oxygen reduction reaction (ORR). As a result the catalyst is highly active and stable in both acid and alkaline electrolytes."

According to the news editors, the research concluded: "The synthetic approach, the carbide-based catalyst, the structure of the catalysts, and the proposed mechanism open new avenues for the development of ORR catalysts."
