Abstract
  • The electrochemical properties of RuO2 electrodes are studied by means of cyclic voltammetry, potential step, and impedance measurements in aqueous 0.5 mol/dm3 H2SO4 as a supporting electrolyte solution and applying the hanging electrolyte meniscus technique. Two types of the electrodes are used: bulk \"asgrown\" single-crystal having (101) exposed interface and 500 nm film produced by reactive RF magnetron sputtering at 450 °C. The surface structure of the RuO2 electrodes prepared by different techniques is defined from X-ray LAUE backscattering. Experimental data show that, for both RuO2 electrodes, the charging components include a slow diffusion-controlled contribution, due to proton injection-ejection. The diffusion characteristics and the diffusion coefficients for the same electrodes are estimated and reported. (literal)
