ELECTRODE

摘要

The present invention relates to a method of preparing an electrode comprising providing an electrode substrate, depositing on said electrode substrate a first substantially aqueous coating solution comprising precursors of a valve metal oxide and of at least two platinum group metal oxides, treating the first coating solution to provide a first metal oxide coating layer on the electrode substrate, depositing on said first coating layer a second substantially organic coating solution comprising precursors of a valve metal oxide and at least one platinum group metal oxide, wherein at least one of the precursors is in organic form, treating said second coating solution to provide a second metal oxide coating layer on the first coating layer. The invention also relates to an electrode obtainable by said method, and the use thereof.
