Data on Chalcogens Described by Researchers at Hong Kong University of Science and Technology

June 17, 2014

By a News Reporter-Staff News Editor at Life Science Weekly -- Current study results on Chalcogens have been published. According to news originating from Hong Kong, People's Republic of China, by NewsRx correspondents, research stated, "Nitrogen-doped CoO (N-CoO) nanoparticles with high electrocatalytic activity for the oxygen-reduction reaction (ORR) were fabricated by electrochemical reduction of CoCl2 in acetonitrile solution at cathodic potentials. The initially generated, highly reactive nitrogen-doped Co nanoparticles were readily oxidized to N-CoO nanoparticles in air."

Our news journalists obtained a quote from the research from the Hong Kong University of Science and Technology, "In contrast to their N-free counterparts (CoO or Co3O4), N-CoO nanoparticles with a N content of about 4.6% exhibit remarkable ORR electrocatalytic activity, stability, and immunity to methanol crossover in an alkaline medium. The CoNx active sites in the CoO nanoparticles are held responsible for the high ORR activity."

According to the news editors, the research concluded: "This work opens a new path for the preparation of nitrogen-doped transition metal oxide nanomaterials, which are promising electrocatalysts for fuel cells."
