A high-efficiency oxygen evolution electrocatalyst based on a Co3[Co (CN)6]2@NiFe LDH composite material

The flower-like Co-PBA@NiFe-LDH-30 demonstrated remarkable electrochemical performance with a lower overpotential of 253 mV at 10 mA cm −2 and a smaller Tafel slope of 54 mV dec −1 during the OER process.
