Electrocatalytic oxidation of hypophosphite on nickel electrode - In situ UV-Vis spectroscopic study
- 化学化工－已发表论文 
The electrocatalytic oxidation of hypophosphite on a nickel electrode has been studied by means of in situ UV-Vis subtractive reflectance spectroscopy. An absorbency band around 245 nm, which was ascribed to the formation of an intermediate, (PHO2-)-P-., was observed in the electrocatalytic oxidation process. Accordingly, the electrocatalytic oxidation of hypophosphite might undergo a H abstraction of hypophosphite from the P-H bond to form the phosphorus-centred radical (PHO2-)-P-.. which is subsequently electrooxidized to the final product, phosphite.
