Preparation of nanostructured nickel aluminate spinel powder from spent NiO/Al2O3catalyst by mechano-chemical synthesis

Publication year: 2011 Source: Advanced Powder Technology, Available online 9 December 2011 M.K. Nazemi, S. Sheibani, F. Rashchi, V.M. Gonzalez-DelaCruz, A. Caballero In this paper, the possibility of mechano-chemical synthesis, as a single step process for preparation of nanostructured nickel aluminate spinel powder from NiO/Al2O3spent catalyst was investigated. Powder samples were characterized in terms of composition, morphology, structure, particle size and surface area using complementary techniques such as X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), differential thermal analysis (DTA) and volumetric adsorption of nitrogen
