Effect of Bi modification on Pt single crystals towards the glycerol electrooxidation in alkaline media

Resumo

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.
