[0022] (4) Preparation of active coating: Extract ruthenium-titanium oxide nanopowder and 85-75mol% iridium-tantalum active slurry according to 15-25mol% of the total molar amount of active material, and mix ruthenium-titanium oxide nanoparticles into iridium In the tantalum oxide active slurry, fully stir, coat on the etched titanium substrate, heat and solidify at 110°C, oxidize and sinter in a box furnace at 530°C for 10 minutes, cool down and then coat, heat treatment , out of the furnace and cooled, repeated 10-15 times in total, and finally annealed at 530° C. for 1 hour to obtain an iridium-tantalum oxide active-coated titanium anode embedded in ruthenium-titanium oxide.
[0023] The present invention obtains an iridium-tantalum oxide active titanium anode embedded with a ruthenium-titanium oxide nanostructure through the above implementation. Studies have shown that the refinement of grains and the increase of grain boundaries can effectively increase the active center...

[0026] The preparation of the iridium-tantalum active oxide-coated electrode material with the addition of 18mol% inserts is carried out in the following steps:
[0027] (1) Preparation of ruthenium titanium oxide slurry: use RuCl 3 and TiCl 3 As the source material, each source material was weighed according to the ratio of Ru:Ti molar ratio of 3:7, and dissolved in butanol respectively, the concentration was controlled at 0.25mol / L, and after each source material was fully dissolved, the two were mixed evenly to obtain Ruthenium titanium oxide active slurry;
[0028] (2) Sintering preparation of ruthenium-titanium oxide nanoparticles: quantitatively extract the ruthenium-titanium oxide active slurry, heat and solidify at 90°C, take it out and grind it, then oxidize and sinter it in a box furnace at 395°C, cool it out of the furnace, and after grinding, An intercalation of ruthenium titanium oxide with a nanoscale of 14 nm was obtained.
