Interaction of Carbon Monoxide with a Nano-Structured Copper-Nickel Coating on Graphite in the Presence of an Electric Field

The influence of the electric field on the interaction of CO with oxidized copper-nickel nanoparticles is studied. It is established that the restoration of the surface of nanoparticles is possible at potentials of φ ≤ +5 V applied to the sample relative to the ground potential, and at φ ≥ +5 V it i...

Beschreibung
Zusammenfassung:The influence of the electric field on the interaction of CO with oxidized copper-nickel nanoparticles is studied. It is established that the restoration of the surface of nanoparticles is possible at potentials of φ ≤ +5 V applied to the sample relative to the ground potential, and at φ ≥ +5 V it is difficult. The most probable mechanism of the influence of the electric field on the reduction rate of the surface oxide is related to the spatial orientation of CO molecules.
