      abstract     = {Tailoring a highly active and stable alkaline
                      electrocatalyst endowed with an ultra-low electron transfer
                      energy barrier for hydrogen/oxygen evolution reactions
                      (HER/OER) has remained elusive to date. Herein, a
                      defect-rich nanoporous Co$^{2+d}$ -incorporated RuO$_2$
                      (Co/RuO$_2$) catalyst was proposed that offered low
                      overpotential and good stability for alkaline HER/OER.
                      Ov–Ru–O–Co coordination under the electron coupling
                      constructed by slight anchoring of Co$^{2+d}$ at Ru$^{4+d}$
                      sites played a pivotal role in optimizing the reaction
                      energy barrier of the intermediates. Theoretical
                      calculations suggested that Ov–Ru–O–Co coordination
                      effectively optimized the primary active site by modulating
                      the electron structure and position of the d-band center.
                      This refinement enhanced the adsorption/desorption of
                      reactive species, facilitating the overall progression of
                      the catalytic reactions. Consequently, the optimal
                      Co/RuO$_2$-1/50 catalyst achieved an ultralow overpotential
                      at 10 mA cm$^{−1}$ , an impressive Tafel slope for both
                      HER (26 mV, 54 mV dec$^{−1}$ ) and OER (243 mV, 88 mV
                      dec$^{−1}$ ) and an outstanding stability for over 100 h
                      for OER. This work offers a practical roadmap for the
                      development of noble metal-based electrocatalysts that
                      exhibit high activity/stability for alkaline HER/OER.},
