Sažetak
Electrochemical charging/discharging reaction of hydrous ruthenium oxide was studied by cyclic voltammetry and electrochemical quartz-crystal nanobalance (EQCN) in sulfuric acid as well as in neutral solutions of Na2SO4 and K2SO4. The ruthenium oxide electrode was prepared by attaching the ruthenium oxide particles on gold covered quartz electrode. The results show that the specific capacitance as well as the apparent molar mass of exchanged species depends on the scan rate. The existence of different mechanisms of the redox reaction depending on the potential range was revealed. The results were interpreted with two different charges, one leading to the mass release and another to the mass loss upon oxidation, taking place simultaneously during the oxidation/reduction reaction of ruthenium oxide.
