Though titanium has extraordinary erosion resistance, when using as electrode separately, the conductive effect in electrolytic solution is undesirable.Though rhodium, iridium have good anti-corrosion and electroconductibility, and have good electrocatalysis effect, too expensive.
Compare with existing electrode, the utlity model has following advantage:
1) because the utility model adopts titanium to make electrode base board, adopt thermal decomposition method to prepare the surface coating that crystal grain is the rhodium iridium oxide of 10～25nm on the electrode base board surface, and electrode shape can be sheet, netted or circular-arc etc., therefore not only have fabulous erosion resistance, and have good electrical conductivity and electrocatalysis characteristic.
2) erosion resistance is strong, and long service life, surface coverage have and reach 86000～113000h the work-ing life of the titanium electrode of nanometer rhodium iridium coatings.
3) can dwindle the size of electrode significantly, reduce the cost of electrode.
4) overpotential is low, electrical efficiency is high, and the nanometer rhodium iridium coatings has very strong electrocatalysis, and the electrochemical reaction overpotential is reduced greatly, reaction fast rapid-result hundred times even thousand times of increases, and operating voltage is lower, and energy consumption reduces significantly.As the electrolytic cleaning seawater, its operating voltage is 3.8～6.5V, ton water power consumption 0.0057 degree; Electrolysis printing and dyeing mill is through the dyeing waste water (COD is 300, and turbidity is 3.9, and colourity is 4) of advanced treatment, and 2min just can make the colored component in the waste water decompose fully, more than the COD drop by half.
