英文摘要: The adsorption of CO2 on Ba0.5Sr0.5Co0.8Fe0.2O3-delta (BSCF) perovskite oxides in the absence and presence of O-2 and H2O at various temperatures was investigated by temperature programmed desorption (TPD). XRD was used to characterize the phase of the samples before and after adsorption. No CO2 desorption peak was observed when CO2 was adsorbed on BSCF at room temperature. A CO2 desorption peak from the decomposition of surface Sr0.6Ba0.4CO3 appeared after CO2 was adsorbed at 400-700 degrees C. The reactivity of CO2 with BSCF increased with increasing temperature, and the resulted carbonate became more stable. When CO2 and O-2 were co-adsorbed, the CO2 desorption peak shifted to lower temperature and the peak area decreased compared with when only CO2 was adsorbed, which was due to the competitive adsorption of CO2 and O-2. The adsorption of CO2 on BSCF was promoted in the presence of H2O. A CO(2)2 desorption peak ranging from ca. 250 to 500 degrees C, assigned to the decomposition of the bicarbonate, was observed when H2O was added. The amount of CO2 adsorbed on Ba1-xSrCo0.8Fe0.2O3-delta increased when the barium doping level increased from 0.3 to 1. (C) 2007 Elsevier B.V. All rights reserved.
