Since the use of oriented single crystals as catalysts allows a unambiguous assessment of the effects of surface geometry, the authors have investigated the hydrogenolysis of n-C/sub 4/H/sub 10/ over the close-packed (111) and the corrugated (110)-(1 x 2) surfaces of Ir. The selectivity for C/sub 2/H/sub 6/ production from the hydrogenolysis of n-C/sub 4/H/sub 10/ over Ir catalysts scales with the concentration of low-coordination-number metal surface atoms.
