Iridium nanoparticles were synthesized between graphite layers by thermal treatment of the mixture of iridium chloride (IV) and graphite powder under chlorine atmosphere followed by hydrogen reduction (Ir-GIC). In Ir-GIC samples with 1–6 wt% iridium metal loadings, all iridium nanoparticles with disk-shape (iridium nanodisks) were located between graphite layers; however, iridium nanoparticles on graphite surface were also formed in addition to iridium nanodisks in the Ir-GIC samples with 8 and 10 wt% iridium metal loadings. Iridium nanodisks between graphite layers were highly active for cinnamaldehyde hydrogenation and selective to cinnamyl alcohol compared with the iridium particles on graphite surfaces. Iridium nanoparticles with disk-shape structure were synthesized between graphite layers by thermal treatment of the mixture of iridium chloride and graphite under chlorine pressure followed by hydrogen reduction.
