循环伏安和现场FTIR反射光谱研究甲醛在金电极上的氧化

Abstract

The electro-oxidation of Formaldehyde on a gold electrode in a gold electrode in a solution containing0.1mol ·L -1 Na2 CO3＋0.1mol·L - 1NaHCO3＋0.1 mol·L, - 1 HCHO was investigated bycyclic 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 gold.At lower potentials, the main product of Formaldehyde oxidationwas HCOO-, and at higher potentials, the products HCOO- and CO2 were detected simultaneously.From the results, a possible reaction mechanism was proposed.
