| Abstract: | The electrocatalytic activity for the oxidation of fornaldehyde and formic acid on a Bi-modified platinum(Pt/Biad) was investigated. The results showed that the Pt/Biad electrode was electrocatalytically more active than a Pt electrode in the anodic oxidation of formaldehyde and formic acid. The electrocatalytic activity of the Pt/Biad electrode can be explained in terms of the geometrical effect, which may lead to the inhibition of the formation of the adsorbed poison. The effects of other factors including the concentration of Bi( Ⅲ ) ion and media on the electrocatalytic activity were also studied and discussed. |
