Electron properties of the system of Ni on kieselguhr

The electron properties of industrial nickel-kieselguhr catalyst under the action of reaction, oxidation, and reduction media are analyzed. As was determined after in situ conductometric studies of the surface of Ni/kieselguhr industrial catalyst, the electron properties on the Ni/NiO/SiO2 interface change, due to the nature of both phases: the surface of the catalyst and the given medium (C1–C4 aliphatic alcohols, oxygen or hydrogen). The mechanism of the observed changes, which determine the activity of Ni/kieselguhr catalyst in the transformations of aliphatic alcohols, is considered.
