manganese dioxide reduction by carbon

manganese dioxide reduction by carbon. While manganese compounds was in widespread use among alchemists and glassmakers, it was only in 1774 when manganese as an element was first identified. Johan Gottlieb Gahn was the first one to isolate manganese via the reduction of dioxide with carbon. The metal has since then been used in a wide range of industrial and commercial uses. Practical ...

01/02/2007· Manganese dioxide (MnO 2) was coated on carbon nanotubes (CNTs) by simple immersion of the CNTs into a KMnO 4 aqueous solution. The synthesis mechanism was investigated by in situ monitoring of the reduction potential and pH of the solution and supplementary UV–VIS analysis of MnO 4-ions in the solution. CNTs were found to act as a reducing agent and substrate for the heterogeneous ...
