      abstract     = {This work presents a systematic and detailed investigation
                      of the structural, electronic, and electrochemical
                      properties of Ni–N thin films grown using a reactive
                      magnetron sputtering at partial nitrogen flow (RN2) of 0,
                      15, 50, 75, and $100\%.$ Below RN2 = $50\%,$ the phase
                      formed is metallic Ni with some N atoms occupying
                      interstitial sites. However, when the RN2 exceeds $50\%,$
                      the Ni3N phase sets in, and a fully stoichiometric Ni3N
                      phase is realized at RN2 = $100\%.$ As RN2 increases, the
                      oxidation state of Ni increases and the structural ordering
                      improves, as substantiated by X-ray absorption fine
                      structure and X-ray diffraction analysis. Additionally, hard
                      X-ray photoelectron spectroscopy measurements confirm the
                      formation of a fully stoichiometric Ni3N phase at RN2 =
                      $100\%.$ Finally, the electrocatalytic performance measured
                      through the oxygen evolution reaction clearly demonstrates
                      better performance of Ni3N as compared to pure Ni or other
                      Ni–N phases. This work provides essential building blocks
                      to establish Ni3N as an environmentally friendly, noble
                      metal-free, and earth-abundant catalyst for water splitting
