Findings from Nanyang Technological University Broaden Understanding of Chalcogens

February 11, 2014

By a News Reporter-Staff News Editor at Life Science Weekly -- Fresh data on Chalcogens are presented in a new report. According to news reporting from Singapore, Singapore, by NewsRx journalists, research stated, "The oxygen reduction reaction (ORR) is of high industrial importance. There is a large body of literature showing that metal-based catalytic nanoparticles (e.g."

The news correspondents obtained a quote from the research from Nanyang Technological University, "Co, Mn, Fe or hybrid Mn/Co-based nanoparticles) supported on graphene act as efficient catalysts for the ORR. A significant research effort is also directed to the so-called metal-free oxygen reduction reaction on heteroatom-doped graphene surfaces. While such studies of the ORR on nonmetallic heteroatom-doped graphene are advertised as metal-free there is typically no sufficient effort to characterize the doped materials to verify that they are indeed free of any trace metal."

According to the news reporters, the research concluded: "Here we argue that the claimed metal-free electrocatalysis of the oxygen reduction reaction on heteroatom-doped graphene is caused by metallic impurities present within the graphene materials."
