The electro-oxidation of formaldehyde on a ld electrode in a ld 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 ld. 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.
- Formaldehyde,
- ld electrode,
- Electrocatalytic oxidation,
- Cyclic voltammetry,
- In-situ FTIR spectroscopy
