Findings on Heavy Metals Reported by Investigators at Huazhong University of Science and Technology (Active catalysts based on cobalt oxide@cobalt/N-C nanocomposites for oxygen reduction reaction in alkaline solutions)

By a News Reporter-Staff News Editor at Life Science Weekly -- Current study results on Heavy Metals have been published. According to news reporting originating from Wuhan, People's Republic of China, by NewsRx correspondents, research stated, "Over the past few years, electrocatalysis for the oxygen reduction reaction in alkaline solutions has undergone tremendous advances, and non-precious metal catalysts are of prime interest."

Our news editors obtained a quote from the research from the Huazhong University of Science and Technology, "In this study, we present a highly promising CoO@Co/N-C (where N-C represents a N-doped carbon material) catalyst, achieving an onset potential of 0.99 V (versus the reversible hydrogen electrode (RHE)) and a limiting current density of 7.07 mA center dot cm(-2) (at 0.3 V versus RHE) at a rotation rate of 2,500 rpm in an O-2-saturated 0.1 M KOH solution, comparable to a commercial Pt/C catalyst. The H-2-O-2 alkaline fuel cell test of CoO@Co/N-C as the cathode reveals a maximum power density of 237 mW center dot cm(-2)."

According to the news editors, the research concluded: "Detailed investigation clarifies that a synergistic effect, induced by C-N, Co-N-C, and CoO/Co moieties, is responsible for the bulk of the gain in catalytic activity."
