Abstract
The electron donor properties of MgO powders, activated in vacuo in the temperature range 300–1200 K have been investigated by adsorption of nitrobenzene and some of its para substituted derivatives. The results confirm that the donor properties of MgO are an intrinsic property of the surface, being practically independent of impurity. Two types of nitrobenzene radical were detected: the first one, formed on low temperature activated samples (2– cus, OH–) is presented. The effect of adding Ni2+ ions in solid solution has also been examined.Keywords
