In this work, the precursor NiFe-PBA (NF) was synthesized by a facile coprecipitation method, and then the NiFe-PBA nano-porous material (NFP) was prepared by solvothermal treatment. XRD, SEM, TEM, XPS, BET and electrochemical methods were used to characterize the structure and test the oxygen evolution performance of the synthesized materials. Electrochemical measurement results showed that compared with the precursor NF, NFP exhibited significantly enhanced electrocatalytic performance of oxygen evolution reaction (OER) due to the increase of electrochemical surface area and catalytic active sites. In 1 mol/L KOH aqueous solution, the NFP required an overpotential of only 260 mV to afford the current density of 10 mA/cm2, 18.75% lower than that of the NF (320 mV) precursor, which also outperformed many previously-reported noble-metal-free electrocatalysts and commercial noble-metal-based catalysts, indicative of a promising prospect for application.
