摘要：
The catalytic activity of polycobaltprotoporphyrin(PCoPP)was compared with adsorbedcobaltprotoporphyrin monolayer.The results have shown that PCoPP film shows higher catalyticactivity 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 wasproposed to explain such dependence.The effect of film thickness and solution pH on the stabilityof PCoPP film was studied.
