As the electric current flows, the titanium anode can generate sufficient active substances to accelerate the removal process of pollutants in sewage. In addition, the reaction ability of the titanium anode can be further enhanced by coating noble metal catalysts such as platinum or iridium, making it perform even better when treating specific types of sewage.
In addition to corrosion resistance and electrical conductivity, the mechanical strength of titanium anodes is relatively high. In practical applications, this strength ensures that the anode can withstand the pressure of the generated gas and electrolyte without being easily deformed or damaged, thus maintaining its long-term stability. Combining these characteristics, titanium anodes present an efficient, economical, and sustainable solution in the application of electrocatalytic oxidation of sewage. Therefore, titanium anodes not only perform outstandingly in electrocatalytic reactions but also play a crucial role in promoting the advancement of sewage treatment technology.
