Cyclic voltammetry was used to study the electrooxidation of formaldehyde on crude platinum electrode in acid medium. The effects of support electrolyte concentration and electrode surface structure on the oxidation of formaldehyde were investigated. The spontaneous dissociation of formaldehyde on the rough platinum electrode was investigated. phenomenon. The dissociative adsorption of formaldehyde on rough platinum electrode was studied by confocal microscopy Raman spectroscopy, and the molecular level information of the dissociative adsorption of formaldehyde on the surface of the electrode was obtained. The spontaneous dissociation of formaldehyde on the rough platinum electrode was verified from the molecular level phenomenon.
