Researchers from South China University of Technology Report on Findings in Chalcogens (Iron tetrasulfophthalocyanine functionalized graphene nanosheets for oxygen reduction reaction in alkaline media)

By a News Reporter-Staff News Editor at Life Science Weekly -- Researchers detail new data in Chalcogens. According to news reporting originating in Guangdong, People's Republic of China, by NewsRx journalists, research stated, "A Fe-based macromolecule composite was synthesized by functionalizing graphene nanosheets (GNs) with iron tetrasulfophthalocyanine (FeTSPc), a non-noble electrocatalyst for oxygen reduction reaction (ORR) in alkaline media in a simple and greener way. Utilizing GNs as a support can avoid FeTSPc being washed away from the electrode surface and catalyze ORR in alkaline media."

The news reporters obtained a quote from the research from the South China University of Technology, "The predominant properties of GNs not only make Fe center in the N4-ring protrude to serve as a catalyst, but also increase the active sites, resulting in excellent ORR catalytic activity in alkaline electrolytes. Conversely, by taking advantage of the excellent solubility of FeTSPc which helps to prevent the aggregation of GNs, the composite (demonstrated as GNs-FeTSPc) showed a long-term stability in alkaline aqueous solution and maintained the catalytic activity. Better yet, the composite GNs-FeTSPc is insensitive to CO due to the special structure of FeTSPc and can facilitate ORR with a direct four-electron process which was demonstrated by the rotating disc electrode (ROE) results."

According to the news reporters, the research concluded: "Clearly, our nanohybrid catalysts show great potential in the large-scale practical application of alkaline fuel cells (AFCs)."
