      abstract     = {Ball milling is commonly used to reduce catalyst particle
                      size. However, littleattention is paid to further changes
                      that ball milling can cause to the rest of thecatalysts’
                      physicochemical properties, which can impact their intrinsic
                      catalyticactivity. The effect of ball milling on the
                      physicochemical properties of NiCoO2 ,NiO, CoO, and NiO:CoO
                      mixtures is reported and correlated with their
                      elec-trochemical oxygen evolution reaction (OER) activity.
                      It is also shown thatparticle fragmentation is an inherent
                      consequence of ball milling, but someoxides can also
                      experience a phase transformation. In the case of
                      rocksalt-structured CoO, it is partially or entirely
                      transformed to spinel-structuredCo 3O 4 . Additionally, NiCo
                      2O 4 with a spinel structure can be formed by ballmilling
                      NiO and CoO simultaneously (both rocksalt structures), but
                      only in theabsence of water. The changes impact the
                      electrochemical activity of the initialoxides. Ball milled
                      NiCoO 2 exhibits the highest activity with a mean
                      potentialof 1.563 V at 10 mA cm2 , demonstrating the
                      advantage of having Ni and Co inthe same structure. Although
                      NiCo2O4 is also a binary oxide, the results indicatethat its
                      metal coordination environment makes it intrinsically less
                      active thanNiCoO2 for the OER in alkaline media..},
