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.

摘要

采用循环伏安法研究了甲醛在粗糙铂电极上的电氧化行为。考虑了影响甲醛电氧化行为的两个因素，即支持电解质的浓度和电极表面结构。利用共聚焦显微拉曼光谱原位研究了甲醛在粗糙铂电极上的解离吸附行为，通过循环伏安法发现了甲醛在粗糙铂电极上的自发解离吸附行为，并通过原位拉曼光谱在分子水平上得到了证实。
