Abstract:
The electrooxidation behavior of HCHO on a roughened platinum electrode was studied by cyclic voltammetry. Two factors that influence the electrooxidation behavior of HCHO, i.e. the concentration of the supporting electrolyte and the structure of the electrode surface were taken into account. The dissociative adsorption behavior of HCHO on a roughened platinum electrode was investigated by confocal microprobe Raman spectroscopy in-situ, and the spontaneous dissociative adsorption behavior of HCHO on a roughened platinum electrode was found by CV and was confirmed at the molecule level by in-situ Raman spectra.

The process of oxidation in a chemical reaction is observed in any of the three forms:
Oxidations of Aldehydes and Ketones to Carboxylic Acids
Aldehydes readily undergo oxidation in strong oxidizing agents such as potassium permanganate and chromic acid. The oxidation can also be carried out using mild oxidizing agents such as silver oxide. In fact, aldehydes can be easily oxidized...
