Abstract Anisotropic structure analyses for [CoOx]/α-Al2O3 (0001) and [Co3O4]n /α-Al2O3 (0001) which were derived from Co2(CO)8/α-Al2O3 (0001) were performed by a polarized total-reflection fluorescence extended X-ray absorption fine structure (EXAFS) technique. Both s- and p-polarized EXAFS data revealed that the cobalt atoms of [CoOx] were located on three-fold hollow sites of α-Al2O3 (0001) in a monomer form and that a thin spinel structure [Co3O4] grew with the (001) plane parallel to α-Al2O3 (0001).
