Abstract
The FeNiMm (Mm = rare earth metals) electrodes have been successfully prepared by vacuum induction melting (VIM) technique and used to be active cathodes in chlor-alkali industry for the first time. The alloys are found that Mm content and Fe content has significant impact on the polarization characteristics of the FeNiMm electrodes. With the increasing of Mm content, the η200 change a little but the apparent exchange hard, and increasing the content of Fe and decreasing the content of Mm will have a negative effect on the electrocatalytic performance. Fe84.50Ni7.72Mm7.72 was found to yield the highest intrinsic electrocatalytic activity. On the power interruption term, the cathodes exhibit excellent resistivity against repeated power interruptions.
