Abstract
The high demand for the biodiesel has increased the glycerol (GlOH) generation, since it is a co-product of biodiesel production, surpassing the industrial demand. In this context, the glycerol electrooxidation reaction (GER) is an interesting option for its chemical valorization, generating high value-added products. In the present work, we studied the GER on different surfaces of Pt single crystals modified with bismuth to understand the effect of the catalyst structure on the activity and reaction pathways.
Highlights
The increasing demand for biodiesel has increased the glycerol (GlOH) generation, since it is a coproduct of its synthesis
This work intends to study the glycerol electrooxidation reaction (GER) in alkaline media using Pt single crystals of the main crystallographic orientations modified with bismuth
We observed that Pt(100) shows the highest current densities and Pt(110) the lowest onset potential without the Bi modification
Summary
The increasing demand for biodiesel has increased the glycerol (GlOH) generation, since it is a coproduct of its synthesis. This increasing in the availability of GlOH surpassed the industrial demand. Many research groups started to investigate alternative uses for this excess GlOH1.
