2090.     LEIDHEISER, H., JR., AND GWATHMEY, A. T.  Selective Deposition of Carbon on the (111) Face of a Nickel Crystal in the Catalytic Decomposition of Carbon Monoxide.  Jour. Am. Chem. Soc., vol. 70, 1948, p. 1206.

        Single crystal of Ni was carefully machined to a spherical shape and mechanically and electrolytically polished.  Previous studies have shown that this treatment produces a smooth, strain-free surface whose crystalline orientation is the same as that of the bulk of the crystal.  CO reacts with this surface and deposits C only on the (111) planes.  The authors suggest that this specificity of the (111) plane for the reaction is due to the fact that most of the atoms of the basal plane of graphite can be made to coincide with little distortion with those of the (111) plane of Ni.
