Energies of Electronic States of Ni (II) Ion in NiO-Al2O3 Catalyst Prepared by Impregnation

Abstract

The behavior of NiO‐Al2O3 catalysts is strongly dependent on the preparation method, as well as on pretreatment conditions. In the present work we investigated the influences of Ni(II) ion on NiO‐Al2O3 catalysts properties due to the preparation by impregnation method. Based on experimental diffuse reflectance spectroscopy (DRS) data of electronic d‐d transitions of Ni (II) promoter ion the energies of electronic states in spinel‐like structure were calculated, and the most probable scheme of molecular orbital have been proposed.
