Co-loading of Pt and Fe on H-type *BEA zeolite (H-*BEA) helped us to stabilize Pt in a highly dispersed state, while Pt was aggregated on the outer surface of H-*BEA in the absence of Fe. Since highly dispersed Pt caused by Fe co-addition resulted in preferred balance between hydrogenating and acidic functions, Pt and Fe co-loaded H-*BEA provided high isomer selectivity in n-heptane conversion in comparison with only Pt loaded H-*BEA.
