The results of an investigation of the capacitive characteristics of sol- -gel-processed titanium- and carbon-supported electrochemically active noble metal oxides, as representatives of porous electrode materials, are presented in the lecture. The capacitive properties of these materials were correlated to their composition, the preparation conditions of the oxides and coatings, the properties of the carbon support and to the composition of the electrolyte. The results of the electrochemical test methods, cyclic voltammetry and electroche- mical impedance spectroscopy, were employed to resolve the possible physical structures of the mentioned porous materials, which are governed by the con- trolled conditions of the preparation of the oxide by the sol-gel process.
