One‐step Synthesis and Chemical Characterization of Pt–C Nanowire Composites by Plasma Sputtering

Abstract

Plasma increases activity: A one-step synthesis of Pt-C nanowire composites using a plasma co-deposition method is reported. Electrodes with a very low Pt loading can be obtained. Pt particles with sizes ranging from 1 to 2 nm are decorating the columnar carbon nanostructures because of strong interactions. The composite microstructure is responsible for a very high metal utilization rate as exemplified by reactions occurring in fuel cell electrodes.

Molecular dynamics simulations of supported metal nanocatalyst formation by plasma sputtering

“…It can be seen from the figure, that for all three investigated kinetic energies, film-like thin films with nanofeatures are formed, and the film morphology closely follows the substrate morphology. The Pt-atoms are also observed to penetrate the amorphous carbon pores, in good agreement with experiments [17,[82][83][84].…”

Advanced catalytic layer architectures for polymer electrolyte membrane fuel cells

“…Ultra low loading catalytic layers prepared by Pt and C co‐sputtering show very high Pt utilization efficiency and high specific activity. The latter was recently attributed to a strong interaction between Pt and carbon . Unfortunately, to the best of our knowledge, no durability data have been reported for these catalytic layers.…”

The template-assisted electrodeposition of platinum nanowires for catalytic applicati

“…Although various techniques such as electron-beam deposition [8], solvothermal synthesis [9], physical vapor deposition [10], electron beam lithography [11] and plasma sputtering [12] have been applied to fabricate Pt NWs, electrodeposition [13] has been proven as the most commonly used deposition method due to its low cost and high productivity [14]. In particular, the templatebased electrodeposition of Pt NWs has been established as an effective method due to its simplicity and high-yielding process.…”
