Cathodic electrosynthesis of TiO2, RuO2 and composite RuO2-TiO2 films
on Pt substrates was performed via hydrolysis of TiCl4 and RuCl3 . nH(
2)O salts dissolved in water or mixed methyl alcohol-water solvent. Th
e weight of the TiO2 and RuO2 deposits was studied versus the duration
of deposition. The crystallization behavior of the deposits has been
studied. A possible mechanism of electrosynthesis is discussed. (C) 19
