| Abstract: | The electro-oxidation of formaldehyde on a gold electrode in a gold electrode in a solution containing 0.1mol •L -1 Na2CO3＋0. 1mol•L - 1NaHCO3＋0. 1 mol•L - 1 HCHO was investigated by cyclic voltammetry and in -situ FTIR spetroscopy . The experimental results demonstrated that the oxidation of formaldehyde at different potential range connected with different surface species of gold. At lower potentials, the main product of formaldehyde oxidation was HCOO-, and at higher potentials, the products HCOO- and CO2 were detected simultaneously. From the results, a possible reaction mechanism was proposed. |
