Single crystal surfaces of platinum were used to study the conversion of catalyzed n-hexane and n-heptane at atmospheric reactant pressures. The rates for dehydrocyclization are five to seven times greater on the (111) orientation crystal face than on the (100) platinum surface, and the presence of atomic steps increases even further this structural selectivity. Conversely, the isomerization rates of neo-pentane and isobutane are markedly faster on the (100) crystal face of platinum than on the (111) surface. The implications of these results to catalyst fabrication and regeneration are discussed.
