To alleviate environment issues derived from CO₂ emission, developing effective and economical methods for CO₂ capture has attracted much attention for decades. Metal-organic frameworks possess high porosity and stability, which is favorable to the adsorption of small molecules. Herein, an aluminum-based MOF, aluminum terephthalate [MIL-53(Al)], was synthesized with H₂O and N,N′-dimethylformamide as co-solvent via microwave-assisted method for CO₂ adsorption. The parameters including pre-mixing mode, microwave temperature, microwave power and reaction time were varied to study their influences on crystal structure, morphology and CO₂ adsorption capacity of MW-MIL-53(Al). Wherein, MW-MIL-53(Al) prepared with pre-mixing mode of stirring at 130 °C, 200 W and 3 h presents high crystallinity and rod-like morphology. The synthesized MW-MIL-53(Al) possesses relatively high BET surface area (961 m²/g), pore volume (0.46 cm³/g) and thermal stability (up to 480 °C), and its CO₂ adsorption capacity is 2.16 mmol CO₂/g adsorbent under 25 °C and 0.1 MPa, which is higher than CS-MIL-53(Al) synthesized via conventional solvothermal method at 130 °C for 48 h.

为了缓解CO ₂排放带来的环境问题，开发有效且经济的CO ₂捕集方法几十年来一直备受关注。金属有机骨架具有高孔隙率和稳定性，有利于小分子的吸附。_{在此，以 H 2} O 和N , N'-二甲基甲酰胺为共溶剂，通过微波辅助吸附CO ₂的方法合成了一种铝基 MOF，即对苯二甲酸铝 [MIL-53(Al)] 。改变预混合方式、微波温度、微波功率和反应时间等参数，研究它们对晶体结构、形貌和CO _2的影响MW-MIL-53(Al)的吸附能力。其中，MW-MIL-53(Al)采用130 ℃、200 W、3 h的预混方式制备，具有较高的结晶度和棒状形态。合成的MW-MIL-53(Al)具有较高的BET比表面积（961 m ² /g）、孔容（0.46 cm ³ /g）和热稳定性（最高480 ℃）以及CO ₂吸附能力在25 ℃和0.1 MPa下吸附剂的吸附量为2.16 mmol CO ₂ /g，高于常规溶剂热法在130 ℃下48 h合成的CS-MIL-53(Al)。
