Electrocatalytic glucose oxidation at bimetallic gold–copper nanoparticle-modified carbon electrodes in alkaline solution

Optimal experimental conditions for hydrogen production using low voltage electrooxidation of organic wastewater feedstock

“…3b) is in agreement with the literature data showing that glucose oxidation occurs at a more negative potential on Au than on Pt, Ni, Cu or Fe [35], and that glucose is easily oxidized under alkaline conditions [40,48,49].…”

“…The specific anode material used also depends on the organic compound itself and the interaction mechanisms between the organic and the anode. For example, oxalic acid is oxidized with increasing difficulty on electrode materials having high oxygen affinity [34] while glucose oxidation occurs at more negative potential on gold electrode surface than on any other, such as Pt, Ni, Cu and Fe [35]. The most extensively studied anodic materials are Pt, PbO 2 , IrO 2 , SnO 2 , and conductive diamond films [33].…”

Nickel hydroxide electrodes as amperometric detectors for carbohydrates in flow injection analysis and liquid chromatography

“…Some studies concerning electroadsorption and oxidation of carbohydrates were carried out on highly expensive noble metal surfaces, as Pt, Au, Cu or alloys [14][15][16][17]. Due to the strong adsorption and accumulation of poisonous intermediates potentially fouling the electrode, sophisticated electrochemical techniques, such as pulsed amperometry or differential pulsed amperometry are usually employed.…”

Recent progress in electrochemical oxidation of saccharides at gold and copper electrodes in alkaline solutions

“…Tominaga et al, also reported on composition-activity relationships for AuAg nanoparticles in the oxidation of glucose in alkaline media. Homogeneously bimetallic Au m Ag 100 − m nanoparticles showed improvements in the electrocatalytic activity for glucose and the electrolysis products were dependent on the composition ratio of Ag [59][60][61].…”
