文摘The catalytic activity of polycobaltprotoporphyrin(PCoPP)was compared with adsorbed cobaltprotoporphyrin monolayer.The results have shown that PCoPP film shows higher catalytic activity and stability than monolayer on glass carbon electrode in both alkaline and acid solution. Catalytic activity of PCoPP goes through a maximum with increase of film thickness.A model was proposed to explain such dependence.The effect of film thickness and solution pH on the stability of PCoPP film was studied.
