Abstract

An Ir/g-Al2O3 system with small metal particles was synthesized by impregnating g-Al2O3 with Ir4(CO)12 in cyclohexane, followed by redn. EXAFS measurements unusually flat metal particles which were attached to the g-Al2O3 surface with long Ir-Osupport bonds. The fact that .apprx.3 Ir-O bonds per Ir atom are present points to (111) epitaxy.
