## Description

- description: Ni-based hydroxides are brilliant electrocatalysts for alkaline urea
    oxidation reaction (UOR). Herein, multiple Ni-based hydroxides were investigated
    by electrocatalytic test for UOR performance. Electrocatalytic performance of
    different ratios of NiCo LDHs was further determined to exploring electrochemical
    reaction pathway and thermodynamic mechanism. Results indicate appropriate Co
    element doping content in Ni hydroxide could greatly improve UOR performance.
    Results of XPS and in situ Raman indicate only part of NiCo hydroxides were converted
    to NiCo oxyhydroxides which drive the subsequent UOR. Moreover, electrocatalytic
    UOR on NiCo oxyhydroxides is found in competition with redox of NiCo hydroxides.
    Density function theory (DFT) calculation manifests that the energy barrier of
    UOR on NiCo oxyhydroxides is lower than redox of NiCo hydroxides which become
    the limitation reaction. Energy barrier gap between UOR and redox which provide
    driving force for UOR which is the primary cause of fast kinetic.
