 This research paper discusses the development of a new type of electrocatalyst for water splitting. The electrocatalyst consists of ruthenium and nickel nanoparticles embedded within nitrogen-doped carbon nanofibers. The electrocatalyst has been shown to have excellent performance in both hydrogen evolution and oxygen evolution reactions, making it suitable for use in a hydrogen fuel cell. Additionally, the electrocatalyst requires less energy to operate than other similar materials, making it more efficient and cost-effective.
