Abstract
We have investigated the hydrogenolysis of various short-chain alkanes on the Ir(111) and Ir(110)-(1×2) surfaces. A striking correlation has been discovered between the selectivity for ethane production from the hydrogenolysis of n-butane over Ir catalysts and the concentration of low-coordination-number metal surface atoms. This result is best interpreted as a manifestation of the occurrence of a particular adsorbed reaction intermediate on the Ir(11O)-(1×2) surface, namely, a metallacyc1e pentane. The formation of this intermediate is sterically forbidden on the Ir(111) surface.
