      abstract     = {Iridium is considered the state-of-the-art electrocatalyst
                      for the oxygen evolution reaction (OER) in acidic media
                      owing to its considerably high activity and stability, yet
                      it is a raw material that is expensive and rare. Here we
                      present a synthesis of a bimetallic hollow aerogel structure
                      based on iridium and nickel prepared by a very simple and
                      environmentally friendly method. Our electrocatalyst was
                      evaluated for the OER in a single electrolysis cell, and it
                      showed an improvement in electrocatalytic performance over
                      time, reaching the current density of commercial IrO2 after
                      500 h of the stability test, despite half the catalyst
                      loading. Our innovative synthesis approach provides the
                      flexibility to tailor and improve the aerogel structures for
                      other electrochemical devices as well, for example,
                      photoelectrolysis, sensors, and more. In addition, we
                      believe that this study can lead to a better understanding
                      of the fundamental behavior of bimetallic electrocatalysts
                      consisting of mixed compositions with transition metals.},
