Abstract
Modifications of nanocrystalline RuO2 and Ru films, chemical-vapor deposited on Ti substrates, are studied inaqueous media, at the initial stages of electrocatalytic O2 evolution. The microstructure, composition andmorphology of the films are examined ex situ by X-ray diffraction (XRD), X-ray photoelectron spectroscopy(XPS), secondary ion mass spectrometry (SIMS) and atomic force microscopy (AFM). Results concerning theinfluence of electrochemical processing on the chemico-physical properties and electrode behavior are presentedand discussed.File in questo prodotto:
