Ethylene glycol, 2-propanol electrooxidation in alkaline medium on the ordered intermetallic PtPb surface

Glycerol electrooxidation on Pd, Pt and Au nanoparticles supported on carbon ceramic electrode in alkaline media

“…9b indicates that at potentials À0.15 and À0.1 V vs. SCE, glycerol oxidation on PtjCCE shows negative impedance behavior. This phenomenon was also observed previously in the oxidation of alcohols on Pt-based electrodes, and generally ascribed to the adsorption of reaction intermediates on the catalyst surface [29,30]. When the potential increases, the impedance changes form negative to positive.…”

3D Platinum–Lead Nanowire Networks as Highly Efficient Ethylene Glycol Oxidation Electrocatalysts

“…Pt was proved to be an effective component for ethylene glycol oxidation reaction (EGOR) . However, the limited reservoir of scarce Pt and the susceptibility to poisonous intermediate species heavily prevent its practical application .…”

Insight into the Electrooxidation Mechanism of Ethylene Glycol on Palladium‐Based Nanocatalysts: In Situ FTIRS and LC‐MS Analysis

“…Platinum and gold-based catalysts have long been used in the first approach, leading to CÀ C bond cleavage products and particularly CO 2 . [3][4][5][6][7][8][9][10][11][12][13][14][15][16] In acid media, Xin et al [17] have observed that for EG oxidation, Pt catalysts exhibited higher catalytic activity than Au. Indeed, in these electrolytes, CO or CO-like intermediates were strongly adsorbed on the active sites of the Pt electrode, resulting in catalyst poisoning; while Au was nearly inactive due to its weak adsorption capability.…”

“…While total oxidation of this diol to CO 2 (or carbonate) involves ten electrons, another route could exchange fewer electrons, but keep intact the skeleton of the molecule in order to supply energy to low‐power devices and at the same time recover platform molecules. Platinum and gold‐based catalysts have long been used in the first approach, leading to C−C bond cleavage products and particularly CO 2 [3–16] . In acid media, Xin et al [17] .…”
