A Highly‐Efficient Oxygen Evolution Electrocatalyst Derived from a Metal‐Organic Framework and Ketjenblack Carbon Material

The composite of the metal-organic framework (MOF) Ni(Fe)-MOF-74 and highly conductive carbon material ketjenblack (KB) could be easily obtained from in-situ MOF synthesis in a one-step solvothermal reaction. features remarkable electrochemical oxygen evolution reaction (OER) performance where overpotential at 10 mA/cm2 current density 1.7 VRHE are recorded as 0.274 650 mA/cm2, respectively, 1 mol/L KOH. In particular, activation nickel-iron clusters under an applied anodic bias steadily boosts OER performance. Although goes through some structural modification during measurements, stabilized optimized shows excellent This simple strategy to design highly-efficient electrocatalysts, utilizing readily available precursors materials, will leverage use diverse complexes into electrode fabrication with high energy conversion efficiency.
