Voltametrijska i EQCM istraživanja površinskih oksidacijsko/redukcijskih procesa elektrodeponiranog rodija u kiseloj otopini

Simultaneous measurements of electrodeposited rhodium in sulfuric acid by cyclic voltammetry and electrochemical quartz crystal microbalance show the presence of sulfate/bisulfate adsorption in the hydrogen ionization region. The adsorption process is continued in the double-layer region. The surface oxidation involves water from the porous electrode layer and, at more positive potential, water from the bulk solution. When the adsorbed and "layer" water were involved in the electrochemical reaction, the electrochemical process was reversible, accompanied by a small hysteresis in the weight-potential curve. At more anodic potential a larger hysteresis was detected.
