Distribution maps of carbon deposited on nickel particles were obtained by micro-Raman spectroscopy. Nickel film was prepared on the oxide substrates of yttria stabilized zirconia (YSZ) and gadolinia doped ceria (GDC). Carbon deposition was induced by annealing in dry methane for 10 min at both 863 and 933 K. Morphology of nickel film was changed into particles with the size of several ten-nanometer to several micrometer at the edge of the nickel film after annealing. For the nickel/YSZ systems, carbon thoroughly deposited on all of sintered nickel particles but was not observed on YSZ surface. For the nickel/GDC systems, carbon was deposited only on the nickel particles with sub-micrometer size.
