Goodman, D W

Kinetic studies over different crystal planes of nickel show the hydrogenolysis of n-butane to be structure sensitive. Significant differences in product formation rates are observed between the Ni(111) and the Ni(100) surfaces. The open (100) surface demonstrates a much higher activity toward rupturing carbon-carbon bonds than does the (111) surface. These results together with previous studies on ethane and cyclopropane hydrogenolysis confirm this result to be a general one. Furthermore an excellent comparison of the product distribution as a function of temperature between a Ni(100) catalyst and a polycrystalline nickel catalyst suggest that (100) facets dominate the chemistry of the polycrystalline surface.
