    Abstract: The electrochemical activities, of Ru-Ti binary-oxide electrodes synthesized by sol-gel and traditional methods were compared with each other (using cyclic voltammetry and AC impedance techniques) so as to examine their ability to evolve chlorine and oxygen in 1M NaCl and 1M H2SO4 solutions, respectively. The morphologies and structures of binary-oxide electrodes were also investigated by scanning electron microscopy (SEM) and x-ray diffraction (XRD). The results of q* indicated that the electrochemically active surface area or the number of active sites of Ru-Ti binary-oxide electrodes synthesized by the sol-gel method was larger than that obtained by the traditional methods for both chlorine and oxygen evolution. The results of R(ct) also demonstrated that the electrochemical activity of Ru-Ti binary-oxide electrodes synthesized by the sol-gel method was better than that obtained by the traditional methods for both chlorine and oxygen evolution. The inverse of q*R(ct) was taken as an apparent site activity of the electrode surface. The apparent site activity of electrodes synthesized by the sol-gel method was found to be slightly smaller than that by the traditional method. Although the distribution of the crack size of the electrode surface depended insignificantly on the methods of preparation, the crevice area or real surface area of electrodes synthesized by the sol-gel method was found to be larger than that obtained by the traditional method.
