CORRELATION OF THE SURFACE STRUCTURE OF THE RuO2/TiAND TiO2 /TiFILMS WITH ELECTROCHEMICAL IMPEDANCE DATA

The surface structure and nature of the capacitance formation RuO2/Ti TiO2 /Ti films are discussed. factors affecting reversibility adsorption-desorption processes oxygen on described. influence geometry pore, ruthenium content, thickness films, value oxide was studied using electron microscopy electrochemical impedance spectroscopy. changes in pore content their depending Ru concentration fixed by microscopy. changing dispersion a wide frequency range used to obtain 3D images film's surface. A scheme adsorption-absorption ratio relation pore’s proposed. study composition, morphological behaviour determined impact shape oxygen, which regulated technical data sensors. By range, it proposed It found that decrease DEL has following relationships: large V-shaped pores boundary titanium base film > small film, rectangular-shaped film. is dependent ration films. So, possible change properties sensors regulation content.
