      abstract     = {Efficient catalysts made of cheap and abundant metal ions
                      are in need to overcome the sluggish kinetics of the anodic
                      water oxidation reaction. The development of an inexpensive
                      catalyst with improved performance is key to produce
                      hydrogen by the electrolytic water splitting reaction. The
                      user friendly chemical solution deposition method was
                      applied to prepare films with predecided mole concentrations
                      of copper and nickel. The mixed metal oxide with equal mole
                      ratio of Cu:Ni (1:1) achieved the maximum activity with the
                      onset of water oxidation at overpotential of 0.40 V (1.63 V
                      vs RHE) and achieved the current density of 1 mA/cm2 at an
                      overpotential of 0.420 V at pH 13. The activity of this
                      combination is attributed to the copper facilitated in-situ
                      formation of a layered nickel oxy-hydroxide structure. The
                      presence of both metal ions was found to be necessary
                      indicating a synergy between Cu and Ni for the oxygen
                      evolution reaction. The present work representing the simple
                      synthesis process of the catalyst with the improved water
                      oxidation activity is a promising step to develop electrodes
                      for water electrolysis.},
