Reactions of n-hexane on three bimetallic (alloy) systems: Pt-Re, Pt-Ir, Pt-Co have been studied with sulphur-free and sulphided catalysts. A shift is observed in the selectivity pattern from “metallic: (on sulphur free catalysts) to “acid catalysed” reactions (on sulphur modified catalysts), which is explained by the shift in the formation of certain intermediates of the reaction.
