      abstract     = {Water splitting is an environmentally friendly strategy to
                      produce hydrogen but is limited by the oxygen evolution
                      reaction (OER). Therefore, there is an urgent need to
                      develop highly efficient electrocatalysts. Here, NiFe
                      layered double hydroxides (NiFe LDH) with tunable Ni/Fe
                      composition exhibit corresponding dependent morphology,
                      layered structure, and chemical states, leading to higher
                      activity and better stability than that of conventional NiFe
                      LDH-based catalysts. The characterization data show that the
                      low overpotentials (249 mV at 10 mA cm–2), ultrasmall
                      Tafel slopes (24 mV dec–1), and high current densities of
                      Ni3Fe LDH result from the larger fraction of trivalent Fe3+
                      and the optimized local chemical environment with more
                      oxygen coordination and ordered atomic structure for the
                      metal site. Owing to the active intermediate species,
                      Ni(Fe)OOH, under OER conditions and a reversible dynamic
                      phase transition during the cycling process, the Ni3Fe LDH
                      achieves a high current density of over 2 A cm–2 at 2.0 V,
                      and durability of 400 h at 1 A cm–2 in a single cell test.
                      This work provides insights into the relationship between
                      the composition, electronic structure of the layer, and
                      electrocatalytic performance, and offers a scalable and
                      efficient strategy for developing promising catalysts to
                      support the development of the future hydrogen economy.},
