The effect of an external magnetic field on the interaction of carbon monoxide with hematite

Abstract

The effect of an external magnetic field on the activation energy (E*) of carbon monoxide interaction with hematite under isothermal conditions in the temperature range of 250 to 350 °C has been studied using in situ magnetometry. The dependence of E* of the reaction of magnetite formation on the magnetic field strength in the field strength range from 60 Oe to 3 kOe is shown for hematite nanoparticle samples deposited on 20 nm silica gel. An extreme field dependence of E* was observed.
