 This research has developed a new type of electrocatalyst that combines ruthenium and nickel nanoparticles with nitrogen-doped carbon nanofibers. The resulting material is able to perform both the hydrogen evolution reaction and the oxygen evolution reaction at a much lower voltage than previously used materials, making it ideal for use in a hydrogen fuel cell.
