Glycerol is electro-converted to glycolate with 85% selectivity on carbon nanotube supported Au catalyst (Au/CNT) in alkaline electrolyte at 1.6 V (vs. SHE) under mild reaction conditions (room temperature, atmosphere pressure, water as solvent).
The electrooxidation of ethyleneglycol (EG) and glycerol (G) has been studied: in alkaline media, in passive as well as active directethyleneglycolfuelcells (DEGFCs), and in directglycerolfuelcells (DGFCs) containing Pd‐(Ni‐Zn)/C as an anode electrocatalyst, that is, Pd nanoparticles supported on a Ni–Zn phase. For comparison, an anode electrocatalyst containing Pd nanoparticles (Pd/C) has

The C3selectivity of carbon‐supported Au nanoparticles for glycerol electro‐oxidation was significantly enhanced by the interaction of Au with electro‐deposited Cu species. Notably, the C3selectivity of supported Au nanoparticles doubled after 90 min of Cu electro‐deposition at +0.015 V. This result was obtained if glycerol electro‐oxidation was performed at +0.1 V for 2 h. The most selective catalysts
