Acid–base properties of metallic oxide catalysts studied by conversion of propan-2-ol
Abstract
Conversion of propan-2-ol in the absence of air has been used to characterize the acid–base properties of metallic oxides. Two families of solids were studied: the first, niobic acid and oxides exhibited only acidic properties, i.e. resulted only in formation of propene, the second, mixed cobalt and nickel molybdates in their α or β forms, exhibited acidic and basic properties i.e. resulted in the formation of both propene and acetone. It was also observed that β-phase molybdates are more active and slightly more selective for propene than the α-phase molybdates.
