Abstract

Provided are an electrode and a preparation method and use thereof. The electrode includes a substrate and a catalytic layer; the catalytic layer is positioned on the upper surface and/or the lower surface of the substrate, and the catalytic layer includes a plurality of catalytic layer units with different chemical compositions; an outermost catalytic layer unit in the catalytic layer that is away from the direction of the substrate is an oxide layer containing a first metal element; other catalytic layer units except the outermost catalytic layer unit are oxide composite layers containing a first metal element and a second metal element; the mole percentage of the first metal element in each layer of the catalytic layer units accounted for a total of metal elements in each layer of the catalytic layer units increases layer by layer along the direction away from the substrate. The electrode can be used as an insoluble anode in the electrometallurgy, can reduce the cell voltage to play an energy-saving role while having a long service life in the electrometallurgy process in which the electrolyte contains high concentration of fluoride ion, and the problems of environmental pollution like lead anode and influence on product purity will not occur.
