摘要：The tetragonal and monoclinic phase Li2ZrO3 is synthesized via liquid phase co-precipitation method and characterized with Scanning Electron Microscopy (SEM), Thermal-Gravimetric Analysis (TGA), and high-temperature CO2 adsorption-desorption measurement. The monoclinic Li2ZrO3 sample shows larger particles and more serious agglomeration than that of tetragonal phase Li2ZrO 3 since the higher calcination temperature. The tetragonal phase Li2ZrO3 exhibits more effective CO2 uptake capacity with about 20% weight gain within 60 min at 848 K, while only about 7% weight gain within 120 min for monoclinic phase Li2ZrO3. The multi-cycle CO2 adsorption measurement shows that tetragonal phase Li2ZrO3 also has high satiability, indicating that the tetragonal phase Li2ZrO3 is effective for the CO 2 high-temperature adsorption.
