Abstract

The invention belongs to the technical field of preparation of an insoluble anode in electrochemical industry, and particularly relates to a titanium-based TiNx / IrO2-Ta2O5 coating anode. The titanium-based TiNx / IrO2-Ta2O5 coating anode comprises a titanium base, a TiNx middle layer and an IrO2-Ta2O5 coating, wherein the titanium base is positioned on the inside of the anode, the TiNx middle layer is positioned in the middle of the anode, and the IrO2-Ta2O5 coating is positioned on the outside of the anode; the TiNx middle layer is prepared by carrying out ion nitriding treatment on the titanium base; and the IrO2-Ta2O5 coating is prepared through a thermal decomposition. The titanium-based TiNx / IrO2-Ta2O5 coating anode provided by the invention can achieve the thickness of the TiNx middle layer at 50-200 micrometers and has the advantages of excellent electricity-conducting property and heat-conducting property and corrosion resistance; compared with an anode which is not subjected to nitrizing treatment, the titanium-based TiNx / IrO2-Ta2O5 coating anode provided by the invention achieves more fine surface crack of the IrO2-Ta2O5 coating and no penetrable crack, has larger reaction surface area, can provide more electrochemical reaction places and can be used for effectively enhancing the stability of the anode and prolonging the service life of the anode.

Description

technical field

[0001] The invention belongs to the technical field of insoluble anode preparation in the electrochemical industry, and specifically relates to a titanium-based TiNx / IrO 2 -Ta 2 o 5 coated anode. Background technique

[0002] The anode is a key component in the electrochemical industry, generally divided into soluble anodes and insoluble anodes. Among them, the earliest applications of soluble anodes are graphite anodes and lead anodes. The anode can be divided into a chlorine analysis anode and an oxygen analysis anode according to the different gases released. The graphite anode belongs to the chlorine evolution anode, and the lead alloy anode belongs to the oxygen evolution anode.

[0003] With the continuous development of industry and science and technology, traditional anode materials are increasingly showing their limitations. For example, the corrosion resistance of graphite anode is not very ideal, and the strength is not high; the electrocatal...
