Glycerol electrooxidation in alkaline media on platinum surfaces modified by bismuth

We studied the glycerol electrooxidation reaction (GEOR) on Pt surfaces modified by Bi adatoms to understand the effect of catalyst strucutre on the activity and selectivity. This investigation was performed using a combination of electrochemical (cyclic voltammetry), chromatographic (HPLC) and spec...

Description
Summary:We studied the glycerol electrooxidation reaction (GEOR) on Pt surfaces modified by Bi adatoms to understand the effect of catalyst strucutre on the activity and selectivity. This investigation was performed using a combination of electrochemical (cyclic voltammetry), chromatographic (HPLC) and spectroscopic (FTIR) techniques. Our results show that the presence of Bi blocks the reaction pathways that lead to CO formation, a poisoning intermediate, and increase the production rate of glyceric acid.
