| Abstract: | The effects of smooth platinum electrode(Pt),platinum electrode modified by platinum microparticles[Pt(Pt)] and polyaniline film electrode[PAN(Pt)] on the electrocatalytic activity for oxidation of formic acid have been studied using the cyclic voltammetric method.The different electrocatalytic activities of these electrodes for oxidation of formic acid were compared.The results showed that the current density for electrocatalytic oxidation of formic acid on PAN(Pt) was 3.79×10 -2 mA/cm+2 which was 235,2.3 and 63 times higher than the current density on Pt,Pt(Pt) and Pt PDMA/Pt respectively.The peak potential on PAN(Pt) was 0.16 V lower than that on Pt PDMA/Pt. |
