Recent Studies from Beijing University of Chemical Technology Add New Data to Chalcogens (Promoted Oxygen Reduction Activity of Ag/Reduced Graphene Oxide by Incorporated CoOx)

By a News Reporter-Staff News Editor at Life Science Weekly -- Research findings on Chalcogens are discussed in a new report. According to news reporting originating in Beijing, People's Republic of China, by NewsRx journalists, research stated, "CoOx incorporated in Ag/reduced graphene oxide nanocomposites (CoOx-Ag/rGO) were synthesized through an one-pot solvothermal method. Electrochemical results showed that CoOx nanoparticles could greatly promote dispersion of anchored Ag nanoparticles and increase the limiting current density for the whole CoOx-Ag/rGO nanocomposites when catalyzing oxygen reduction reaction (ORR) in alkaline medium."

The news reporters obtained a quote from the research from the Beijing University of Chemical Technology, "With CoOx formation beside the Ag nanoparticles, a much higher current density and a preferable four-electron pathway were achieved for the CoOx-Ag/rGO nanocomposites. Meanwhile, the CoOx-Ag/rGO nanocomposites showed remarkable long-term stability and tolerance toward methanol than the commercially available 20% Pt/C catalyst."

According to the news reporters, the research concluded: "More importantly, this work could finally lead to a practical significance for developing high-performance bicomponent electrocatalysts with low-cost for fuel cells and relevant electrochemical technologies."
