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