      abstract     = {Efficient oxygen evolution reaction (OER) electrocatalysts
                      are pivotal for sustainable fuel production, where the Ni-Fe
                      oxyhydroxide (OOH) is among the most active catalysts for
                      alkaline OER. Electrolyte alkali metal cations have been
                      shown to modify the activity and reaction intermediates,
                      however, the exact mechanism is at question due to
                      unexplained deviations from the cation size trend. Our X-ray
                      absorption spectroelectrochemical results show that bigger
                      cations shift the Ni2+/(3+δ)+ redox peak and OER activity
                      to lower potentials (however, with typical discrepancies),
                      following the order
                      CsOH > NaOH ≈ KOH > RbOH > LiOH. Here, we
                      find that the OER activity follows the variations in
                      electrolyte pH rather than a specific cation, which accounts
                      for differences both in basicity of the alkali hydroxides
                      and other contributing anomalies. Our density functional
                      theory-derived reactivity descriptors confirm that cations
                      impose negligible effect on the Lewis acidity of Ni, Fe, and
                      O lattice sites, thus strengthening the conclusions of an
                      indirect pH effect.},
