Reactions of three /sup 13/C-labeled methylpentanes, namely, 2-(2-/sup 13/C)methylpentane, 2-(4-/sup 13/C)methylpentane, and 3-(3-/sup 13/C)methylpentane, were performed on a series of Pt-Cu alloy catalysts prepared by coimpregnation in order to determine the mechanistic change in isomerization caused by the dilution of Pt in Cu. The results of this research are explained by an ensemble size effect which causes a shift from multisite mechanisms for isomerization (on Pt-rich alloys) toward one-site mechanisms for isomerization (on Cu-rich alloys).
