Study on polypyrrole as an electrode material in neutral solutions
A study of the polypyrrole (PPy) as an electrode material for cathodic reduction of dioxygen in water solutions depending on the substrate material was carried out. It has been found that the electroactivity of a PPy film strongly depends on the nature of a substrate, especially if the thickness of...

| description | A study of the polypyrrole (PPy) as an electrode material for cathodic reduction of dioxygen in water solutions depending on the substrate material was carried out. It has been found that the electroactivity of a PPy film strongly depends on the nature of a substrate, especially if the thickness of the PPy film is low. The efficiency coefficient of the dioxygen reduction on the Ni⧹PPy electrode is higher than the one on the Pt⧹PPy electrode and achieves 84%. The electroactivity of PPy film falls as a result of cathodic polarization, but it can be regenerated by short anodic polarization pulse. The stability of the PPy film in 0.1 M NaCl is higher than in 0.1 M Na
