Abstract
The progressive diffusion of Ni2+ ions into the MgO matrix, with the consequent formation of an NixMg(1–x)O solid solution, occurring during the air calcination of a 19% Ni/MgO catalyst in the range 400–1000 °C, has been monitored by X-ray diffraction (XRD) measurements using monochromatized non-doublet synchrotron radiation. A solid-state reaction model accounting for the NiO–MgO interaction in supported and mechanically mixed systems is discussed.Keywords
