Glycerol electro-oxidation on a carbon-supported platinum catalyst at intermediate temperatures

KOH-doped polybenzimidazole for alkaline direct glycerol fuel cells

“…The oxidation of glycerol in an alkaline environment has been proved to be especially favourable [35], and so has electrochemical oxidation (in a fuel cell), with very promising results in terms of power and added value products [6,7,28,36,37]. Moreover, in practical terms these advantages are accompanied by a significant weight of fundamental knowledge, accumulated over the last decade, on the glycerol electro-oxidation process [38][39][40][41]. In this scenario, the alkaline polymeric membrane is expected to play a crucial role in the development of alkaline Direct Glycerol Fuel Cells (DGFC), and hence the analysis of its most relevant properties that define the actual performance becomes of interest.…”

A review of recent developments on kinetics parameters for glycerol electrochemical conversion – A by-product of biodiesel

“…3), it was proven that various peaks were obtained at pH 1 which was specified as the best condition for enriched glyc erol conversion reactions with the highest current densities com pared to the neutral and alkaline conditions (Hunsom and Saila, 2015). Though glycerol electro reduction mechanism pathway study is very limited, this reaction preferred acidic medium to pro duce acetol intermediate via dehydration which important for 1,2 propanediol formation (Ishiyama et al, 2013;Lee et al, 2018). From the recent catalytic studies, tungstic acid (H 2 WO 4 ) has a potential role as the medium to reduce glycerol into propanediol compounds, which can be beneficial for 1,3 propanediol formation using the electro reduction reaction (Nakagawa et al, 2014).…”

Oxide (Co3O4, NiO, Mn3O4, MgO) promoted Au/C catalyst for glycerol electrooxidation in alkaline medium

“…Hence, glycerol is a potential liquid fuel for the DAFCs. Pt-based catalysts have been extensively investigated and proved as good electrocatalysts for glycerol electrooxidation [7][8][9][10]. However, high price and limited supply of Pt are major barriers to the development of the DAFCs using the Pt-based catalysts.…”
