Investigators at NIMS Describe Findings in Carbon Monoxide (Fabrication of Ni-Al nanoparticles via vacuum arc plasma evaporation and their catalytic properties for CO oxidation)
Our news journalists obtained a quote from the research from NIMS, "The as-fabricated nanoparticles were composed of Ni, Ni3Al, and a small amount of NiAl, with Al2O3 and NiO phases formed on their surfaces. The nanoparticles exhibited a much higher activity than that of a conventional atomized Ni3Al powder. It was found that the Ni phase is oxidized to NiO during CO oxidation, while the Ni3Al phase remains unchanged."
According to the news editors, the research concluded: "It is likely that the NiO phase serves as the active species for CO oxidation, and the Ni3Al and Al2O3 phases serve as supports for the NiO phase."
