Abstract
Carbon supported NiFe bimetallic catalyst were prepared by a simple one-step calcination process. And the phase, structure, and morphology of the sample were studied and analyzed through XRD, SEM, and TEM, and a carbon supported nickel iron alloy electrocatalyst was successfully prepared. The effect of different NiFe metal ratios on the oxygen evolution reaction performance of Electrolysed water was further investigated. The oxygen evolution reaction activity of Ni2Fe@NC was the most significant. When the current density of 10mA·cm-2 is reached, the overpotential was 330mV, the Tafel slope was 58.9 mV·dec-1. In addition, we studied the stability of Ni2Fe@NC and tested Ni2Fe@NC catalyst for 10000s continuously by using chronoamperometry, demonstrating its excellent stability.
