Cyclic voltammetric deposition of hydrous ruthenium oxide for electrochemical…

Abstract Ruthenium chloride and iridium chloride precursors (denoted hereafter as RuCl3
aH2O and IrCl3
bH2O) reacted with water molecules and transformed into the chloro-oxy-hydroxyl-metal (denoted as Ru(OH)dCl3d
cH2O and Ir(OH)oCl3o
dH2O) structures when they were dissolved in water. The storage time, preheating, and initial pH of the deposition baths were demonstrated to significantly infl…
