Comparison of methanol, ethanol and iso-propanol oxidation on Pt and Pd electrodes in alkaline media studied by HPLC

Tailoring properties of platinum supported catalysts by irreversible adsorbed adatoms toward ethanol oxidation for direct ethanol fuel cells

“…Acetaldehyde and acetic acid have been found as the major products of ethanol oxidation in a wide range of catalysts [3] which limits the potential performance of the fuel cell. In addition, the formation of acetic acid is not desired in a fuel cell because it also causes local changes in the pH of the anode decreasing the membrane life time.…”

Pt catalysts modified with Bi: Enhancement of the catalytic activity for alcohol oxidation in alkaline media

“…In agreement with the results shown previously, the catalytic activity from the Bi adatoms is observed even for low coverages (0.3). Then the oxidation currents appear to increase almost linearly with the amount of Bi at the surface and the maximum is obtained for significantly high 14 coverages. For coverages higher than 0.72 the currents start to decrease.…”

“…Following the procedure previously described [13], prior to the use of the nanoparticles for alcohol oxidation, they were cleaned by CO (AGA, 99.999%) adsorption and stripping [14]. The active surface area of the Pt nanoparticles was determined 6 by the charge involved in the so-called hydrogen UPD region assuming 0.23 mC cm −2 for the total charge after the subtraction of the conventional current attributed to double layer charging contribution [14].…”

“…Similarly to acidic environments, in alkaline electrolytes the majority of the studied catalysts are based in noble metals with special attention for platinum and palladium, mono or multimetalic [12][13][14]. Pt catalysts are considered the most active materials for alcohols electrooxidation in alkaline media due to the capability of Pt to catalyze C-H bond rupture at comparatively low overpotentials.…”

Exceptional enhancement of H2 production in alkaline environment over plasmonic Au/TiO2 photocatalyst under visible light

“…This work was inspired by the growing awareness of the vital role of an alkaline environment for noble metal Au as well as Pt and Pd in showing their excellent electrocatalytic alcohol oxidation performance. [24][25][26][27][28][29][30] Among these noble metal electrocatalysts, Au is a lucky one having photocatalytic performance because of its distinctive SPR effect. It is reasonable that the mechanism of electrocatalytic redox reaction over Au can provide inspiring knowledge to Au-based plasmonic photocatalysis.…”
