3D nanostructured Ce-doped CoFe-LDH/NF self-supported catalyst for high-performance OER

Ce-doping CoFe-LDH nanoneedles were prepared, possessing Ce 3+ and CoFe reaction centers. The promising results are obtained, including a superior low overpotential at 10 mA cm −2 of 225 mV and an outstanding Tafel slope of 34.34 mV dec −1 .
