      abstract     = {The urgent global demand for sustainable energy drives the
                      search for durable and efficient electrocatalysts for water
                      splitting. Cobalt mononitride (CoN) stands out due to its
                      earth abundance, high conductivity, and corrosion
                      resistance, but its thermodynamic instability often results
                      in cobalt-rich secondary phases. Here, we report a scalable
                      reactive cosputtering approach for the controlled synthesis
                      of CoN thin films, along with palladium (Pd) incorporation
                      to enhance activity and stability. Pd doping induces a
                      negative valence state and promotes electron transfer from
                      nitrogen to Pd sites, thereby refining the microstructure,
                      redistributing charge, and shifting the d-band center away
                      from the Fermi level. These synergistic effects reduce the
                      overpotential from 470 to 360 mV at 10 mA·cm–2 in a
                      sample coated on the ITO substrate and deliver markedly
                      improved long-term OER stability with increased
                      catalytically active sites. The turnover frequency showed
                      nearly twice the intrinsic activity with Pd doping. This
                      work establishes Pd-doped CoN as a high-performance, durable
                      electrocatalyst, offering a scalable pathway toward
                      efficient water splitting technologies.},
