Information

  • Carbon in a nickel oxide sample (C 1s forum)

    C 1s spectra was obtained from the surface of a nickel thick sample that was exposed to ultra pure oxygen at 100°C for 8 minutes in the tubular furnace. The peaks at 284.56, 286.50, and 288.15 eV correspond to C-C, C-O, and C=O bonds, all present in adventitious carbon. The peak at 292.62 eV probably is associated to compounds with C-C, C-O and C-H bonds or physisorbed CO2. Finally, the peak at 282.98 eV is diffused carbon, respectively. Data included in a Master Thesis (Guzmán-Bucio, Dulce M. Mecanismo de oxidación de níquel metálico, Cinvestav, Querétaro)
