EXAFS spectroscopy has been used to investigate the dispersion of NiO onto the surface of γ-Al_2O_3. The comparison of the Fourier transformed EXAFS modulations of 7, 13, 18, 26, 35 wt% Ni/γ-Al_2O_3 and 13, 26 wt% Ni/α-Al_2O_3 suggests that NiO can disperse as a monolayer onto the surface of -γAl_2O_3. The Ni—O coordination distance which is near the Ni—O distance in NiO crystal suggests that the Ni ion interacts strongly with the oxygen on the γ-Al_2O_3 surface.
