Trimetallic amorphous catalyst with low amount of platinum: Comparative study for ethanol, bioethanol and CO electrooxidation

Molecular dynamics simulations of supported metal nanocatalyst formation by plasma sputtering

“…As an example of MD simulations of multimetallic catalysts, we here highlight our latest results on sputter deposition of a trimetallic catalyst, which is of interest for reducing the Pt content in fuel cell cathodes for oxygen reduction [95][96][97]. Figs.…”

Review of Low Pressure Plasma Processing of Proton Exchange Membrane Fuel Cell Electrocatalysts

“…Very recently, it was observed that such sputtered nanocatalysts are amorphous at very low loading (10 μg Pt .cm −2 ) and leading to high power density . Correlation between high fuel cell efficiency and catalyst amorphous structure has been independently confirmed in the case of complex Pt alloys for direct alcohol fuel cell …”

“…[33,35] Correlation between high fuel cell efficiency and catalyst amorphous structure has been independently confirmed in the case of complex Pt alloys for direct alcohol fuel cell. [80] Dependence of the plasma sputtering parameters, plasma pressure, substrate bias, . .…”

Synthesis of highly active amorphous platinum-based catalysts for methanol electrooxidation

“…Multimetallic amorphous Pt-based alloys are more forgiving. These Pt-based alloy catalysts often employ transition metals, most commonly nickel (Ni), to induce lattice mismatch in order to achieve stable amorphous structure [60][61][62][63][64][65][66][67] . However, Ni and transition metals in general as an alloying element are not stable at high potential.…”

“…The list of metals which have been alloyed with Pt are extensive, including but not limited to precious metals such as gold (Au) 34 , ruthenium (Ru) 36,38,112 , Pd 41,68 to common transition metal such as Fe 113 , Co 40,113 , copper (Cu) 37,114,115 , Ni 32,33,35,64,65 .…”
