Platinumis the most commonly used catalyst for the electroreduction of oxygen and all of the PGMs reduce oxygen in alkaline media according to the direct four-electron process. At a very low Pt/C ratio, the overall number of electrons exchanged is approximately two due to the carbon contribution...

As for 1, the total number of electrons stored per molecule increases once during the initial 10min and then abruptly decreases down to around 0.1 electrons per molecule at 20min, during which the storage is maximized at 1020min with 0.60.7 electrons stored per molecule, thereby indicating ...
A number of complexes of platinum, in which the metal is in a formally low oxidation state, have been investigated by the ESCA technique. Binding energies of Pt 4f7/2 electrons were obtained and interpreted in terms of the degree of oxidation of the metal by assuming that within the series...
H2O2 selectivity and number of electrons transferred (n) were calculated from RRDE tests (equations 2 and 3), which were carried out by applying 1.2 VRHE on the ring disk of the working electrode at a 900 r.p.m. speed. H2 O2 yield : H2 O2 ð% Þ ¼ 200Â ID IR =N þ ...
Platinum with the atomic number 78 and an atomic mass of 195 in the periodic table. Learn the density of platinum, it’s properties and how it leads to health issues upon exposure to its salts.
(rotating speed: 900 r.p.m., scan range: 0–1.1VRHE). ORR results were presented after subtraction of the currents measured in an N2-saturated 0.1 M HClO4electrolyte to remove capacitances. H2O2selectivity and number of electrons transferred (n) were calculated from RRDE tests (...
This effect was explained by presence of the lone pair electrons of N atoms in the structure of 4-VP that can not only be chelated with metal ions, but also form hydrogen bonds with functional groups such as carboxyl and hydroxyl groups. This Pd(II)-IIPs could be potentially applied for ...
The bipolar plate helps with the conduction of electrons, connecting single cells and directing the flow inside the electrolyzer. The bipolar plate needs high thermal and electron conductivity, low gas permeability and high mechanical and corrosion resistance, which helps increase the electrolyzer's ...
Thermal agitation of electrons in a conductor gives rise to a randomly varying voltage. The average of the square of this voltage is directly proportional to the Kelvin temperature. Properly calibrated, a measurement of the voltage yields the Kelvin temperature. Although the technique requires sophisti...
