以Pluronic F127为模板剂，酚醛树脂为碳源，硝酸镁为客体前驱体，采用固相研磨法制备了有序介孔氧化镁/碳球复合材料。所得材料呈球形，孔径均匀，直径为200 nm，体心立方介观结构孔径为2.6-3.2 nm。当氧化镁含量为7.9wt%时，在273K，1.2bar的温度下，材料对CO2的吸附能力最好，为3.08mmolg−1。
Ordered mesoporous MgO/carbon spheres composites were synthesizedviasolid-state grinding method, in which Pluronic F127, phenolic resol and magnesium nitrate were used as the template, carbon source and guest precursor respectively. The resultant materials showed a spherical morphology with a uniform diameter of 200 nm, body-centered cubic mesostructure of 2.6–3.2 nm in pore diameter. The material with the content of 7.9 wt% MgO exhibited the best CO2adsorption capacity of 3.08 mmol g−1at 273 K, 1.2 bar.
