  • Current Reversal Tolerant Multilayer Material, Method of Making the Same, Use as an Electrode, and Use in Electrochemical Processes
    Publication number: 20230257893
    Abstract: The invention provides an electrode comprising a substrate and a coating on the substrate. The coating comprises a plurality of layers, including the following layers in sequence moving outwardly from the substrate: a base layer comprising an oxide of a valve metal; a lower layer comprising an oxide of a platinum group metal and/or an oxide of a precious metal; and a mixed oxide primary layer comprising both: (i) an oxide of a platinum group metal and/or an oxide of a precious metal, and (ii) an oxide of a valve metal and/or an oxide of a group 15 metal. The base layer is devoid of any platinum group metal oxide, and the lower layer is devoid of any valve metal oxide. The present invention also provides methods of manufacturing such electrodes. Also provide are methods of using an electrochemical cell equipped with a certain multilayer coated electrode.
    Type: Application
