In situ identification of the electrocatalytic water oxidation behavior of a nickel-based metal–organic framework nanoarray
Metal–organic frameworks (MOFs) have been identified as one of the promising electrocatalysts for the oxygen evolution reaction (OER).

| description | Metal–organic frameworks (MOFs) have been identified as one of the promising electrocatalysts for the oxygen evolution reaction (OER). However, direct observation of the electrocatalytic behavior of MOF-based electrocatalysts remains extremely challenging, which is of great significance to understand their electrocatalytic mechanism. Herein, we developed a vertically oriented Ni-based MOF nanosheet array doped with 2.09 wt% Ce (denoted as Ce–NiBDC/OG). Ce–NiBDC/OG displayed a low overpotential of 265 mV to deliver a 10 mA cm
−2
current density for the OER.
In situ
spectroscopy and operando microscopy visualized the phase transformation behavior of Ce–NiBDC/OG to Ce-doped NiOOH induced by electrochemical activation, which was regarded as the real active site. Mechanistic studies revealed that, for the Ce–NiBDC/OG-derived catalyst, the doping of Ce species in NiOOH significantly increased the adsorption of *OH, and further reduced the energy barriers of the rate-determining step (*OH→*O). |
