摘要：

The effect of Fe2O3 dopants (0 - 0.8 mol.%) on ZnO conductivity and its chlorine chemisorption ability has been studied in the temperature range of 20 - 250-degrees-C. Introduction of dopants increases the activation energy of ZnO conductivity and decreases the conductivity. The effective charge of the chemisorbed chlorine species as well as the strength of their bonding to the surface in samples containing Fe2O3 are considerably lower than in initial ZnO, which leads to a decrease of reactivity of the doped catalysts in chlorination.
