Ethylene glycol is simple polyol which is easy to produce from biomass and coal. Selective electro oxidation of ethylene glycol has got great attention to produce high value-added chemicals, such as glycolic acid (GCA), oxalic acid (OA), glyoxylic acid (GOA) and formic acid (FA). In this work, we prepared a Se-doped porous carbon supported Pt catalyst (Pt/SePC) via a modified polyol method for the ethylene glycol conversion to glycolic acid. The 3D porous structure of SePC materials and morphology of Pt nanoparticles were investigated. Selective ethylene glycol oxidation was performed in different applied potential and the conversion and the GCA selectivity were identified using high performance liquid chromatography (HPLC). Glycolic acid was observed as major product at every voltage and both ethylene glycol conversion and selectivity of GCA were modified by doping Se atom in carbon materials. Our study highlights effects of Se doping to carbon for promising chemical transformation of ethylene glycol to glycolic acid. |
