Abstract:

A kind of aniline pentamer with high nitrogen content was used as ligand to prepare Fe/Co-MOF loading on nickel foam through solvothermal method. Fe2P, Co2P, N and P modified carbon material(Fe/Co/P-NPs) was obtained by phosphating reaction with Fe/Co-MOF as metal and carbon sources. Scanning electron microscopy(SEM), transmission electron microscopy(TEM), X-ray photoelectron spectroscopy(XPS) and X-ray diffraction analysis(XRD) were employed to characterize the morphology and structure of the materials. The electrocatalytic activity and stability of the materials were characterized by cyclic voltammetry(CV) and linear sweep voltammetry(LSV). It is found that Fe/Co/P-NPs display good catalytic activity in oxygen evolution reaction, with over potentials of 270 and 300 mV to deliver 10 mA/cm 2 and 100 mA/cm 2 current density, respectively, proving the better activity than that of RuO2. Importantly, it requires 1.48 V to reach the current density of 10 mA/cm 2 and shows good stability in alkaline solution.
