Abstract: For the importance of improve the electro-catalytic activity of titanium anode with chlorine evolution, a type of Pd- PdO nano-particles coating titanium anode was prepared by the method of sol- gel. X-ray diffraction analysis provided information about the composition of the anode. The potential and the cyclic voltammetry of the anode under dif ferent sintering temperature were tested. The results showed that the Pd PdO nano-particles coating titanium anode exhibited obviously good electro-catalytic activity.
