Sažetak
Electrochemical properties of ruthenium modified glass–like carbon, GC, electrodes in H2SO4 solution have been studied by cyclic voltammetry, CV, and electrochemical impedance spectroscopy techniques. Properties of two different GC electrodes (polished and “activated”) were compared. Both electrodes showed a similar CV shape. However, higher surface area and higher quantity of surface oxygen containing species were indicated for „activated“ GC electrode. CV profiles of ruthenium modified GC electrodes, made by electrodeposition of different quantities of ruthenium metal particles on GC substrates, indicated formation of composites. Impedance spectra of all composite electrodes showed parallel impedance responses characteristic for GC support and ruthenium.
