Searching bioalcohols for more sustainable fuel cells: On the electrochemical oxidation of a glycerol platform molecule on gold

In this work, the electrochemical oxidation of a bio-based platform molecule derived from glycerol, namely glycidol, was investigated on gold electrodes and compared to the electrooxidation of glycerol, since both are C3-based alcohols derived from the same renewable biomass source. Cyclic voltammet...
