| Abstract |
Under a corrosive environment, electrodes that are applied in the water-treatment system need not only very high electro-chemical activity for fast reaction, but also high durability for cost saving. Therefore, fabrication condition of iridium electrodes was examined to produce a more durable iridium electrode in this study. Tantalum was selected as a binder to enhance the durability of the iridium electrode. Investigation on the weight ratio between the catalyst and the binder to improve electrochemical activity was performed. Also, to compare the effect of the different coating amount of the catalyst, the result of CV (Cyclic Voltammetry) and EIS (Electrochemical Impedance Spectroscopy) were discussed. Furthermore, ALT (Accelerated Lifetime Test) was designed and applied to the electrodes to determine the conditions for highly durable electrode fabrication. |
