In this paper, MoO3 dispersed on an alumina support was studied. The dispersion threshold was determined by x-ray diffraction and the Mo-O coordination structure was detected by extended x-ray absorption fine structure (EXAFS), which shows that the preferred dispersion phase is made up of [MoO4] polyhedrons.
