Report Summarizes Nitrogen Study Findings from Max-Planck-Institute

June 3, 2014

By a News Reporter-Staff News Editor at Life Science Weekly -- Current study results on Nitrogen have been published. According to news reporting originating from Dusseldorf, Germany, by NewsRx correspondents, research stated, "The type and the amount of functional groups on the surface of carbon nanotubes (CNTs) were tuned to improve the activity of supported Co nanoparticles in hydrogenation catalysis."

Our news editors obtained a quote from the research from Max-Planck-Institute, "Surface nitrogen species on CNTs significantly promoted the decomposition of the cobalt precursor and the reduction of cobalt oxide, and improved the resistance of metallic Co against oxidation in ambient atmosphere. In the selective hydrogenation of nitrobenzene in the gas phase, Co supported on CNTs with the highest surface nitrogen content showed the highest activity, which is ascribed to the higher reducibility and the lower oxidation state of the Co nanoparticles under reaction conditions."

According to the news editors, the research concluded: "For Co nanoparticles supported on CNTs with a smaller amount of surface nitrogen groups, a repeated reduction at 350 degrees C was essential to achieve a comparable high catalytic activity reaching 90% conversion at 250 degrees C, pointing to the importance of nitrogen species for the supported Co nanoparticles in nitrobenzene hydrogenation."
