By a News Reporter-Staff News Editor at Life Science Weekly -- Data detailed on Chalcogens have been presented. According to news reporting out of Oak Ridge, Tennessee, by NewsRx editors, research stated, "Supportless platinum nanotubes (PtNTs) were synthesized by the decomposition of platinum acetylacetonate vapor within anodic alumina templates at 210 degrees C. As synthesized, the nanotubes are nanoparticulate aggregates composed of Pt crystallites approximately 3 nm in diameter and with a range of lengths from 1 mu m to 20 mu m. Annealing treatments result in crystallite growth and morphological evolution of the tubular nanostructures including the development of nanoscale porosity."
Our news journalists obtained a quote from the research from Oak Ridge National Laboratory, "In rotating disk electrode measurements carried out in 0.1MHClO(4), porous PtNTs annealed at 500 degrees C exhibited a specific activity for oxygen reduction of 2390 +/- 423 mu A/cm(Pt)(2) at 0.9 V, comparable to bulk polycrystalline Pt."
According to the news editors, the research concluded: "The electrochemical surface area of the annealed structures was a relatively low 10 m(2)/g, resulting in a moderate overall mass activity of 240 +/- 41 mA/mg(Pt)."
