Characterization of Ce–Mg–O supports
The N 2 adsorption/desorption isotherms and poresizedistributions (PSDs) of 5CeO 2 –5MgO at calcination in temperature range of 550–900 °C are given in Fig. 1 . The
nitrogen molecule in the adsorbed state is 16.2 Å 2 . Pore volumes and poresizedistributions were determined by the BJH method.
