“…Previous experimental studies of bimetallic Pt-Ir catalysts as reforming catalysts have shown that such catalysts are more active and less prone to coke formation compared to pure Pt [27][28][29][30][31]. In contrast to other promoting elements, Ir is unique in that it is capable of alkane activation [29,[32][33][34]. It is also noted that promotion of Ir together with Sn has been shown to significantly improve propane dehydrogenation activity while suppressing hydrogenolysis and 4 other side reactions [35,36].…”

“…[7][8][9][10][11][12] For example, McVicker et al 12 studied the selective rupture of naphthenic rings (methylcyclopentane (MCP), methylcyclohexane (MCH), 1,1-, 1,2-and 1,3-dimethylcyclopentane (1,1-DMCP, 1,2-DMCP and 1,3-DMCP), pentylcyclopentane (PCP) and ethylcyclopentane (ECP)) on Pt/SiO 2 , Pt/Al 2 O 3 , Ni/Al 2 O 3 , Ru/Al 2 O 3 , Rh/Al 2 O 3 and Ir/Al 2 O 3 . Among the mentioned catalysts, Ir/Al 2 O 3 presented the best activity and selectivity for cleavage of non-substituted C-C in five-membered naphthenic rings as MCH and PCP.…”

“…It has been proposed that (ill) crystal faces are inactive toward hydrogenolysis reactions (45-47) and it may be that more (ill) crystal faces are exposed on the more highly sintered films. This would be expected because the The only activation energies reported for iridium were between 46 and 60 kcal/mole and were obtained over supported catalysts at total pressures >10 torr (5,11); the reaction conditions and product distributions for those studies dif fered markedly from those in the present work.…”

“…All of the group VIII metals plus copper and gold have been found to be active for the hydrogenolysis reaction, while only platinum (5)(6)(7)(8)(9). gold (5)I tungsten (8), palladium (10), and iridium (5,11) catalyze the isomerization reaction. Anderson and Avery (?…”
