摘要 利用球磨-水热方法合成了具有高比表面积的氧化镁材料.经正辛基三乙氧基硅烷修饰后,氧化镁的比表面积增加,表面疏水性变强.特别是经0.2 mL硅烷修饰后的氧化镁比表面积高达210.1 m^(2)/g.硅烷对氧化镁表面的修饰极大地提高了材料的CO_(2)吸附性能.在200℃下,经0.1 mL硅烷修饰后氧化镁的CO_(2)吸附量达到69 mg_(CO_(2))/g,是纯氧化镁的3.1倍. MgO with high specific surface area were synthesized by ball milling-hydrothermal methods.Furthermore,after octyltriethoxysilane(OTES)modification,the specific surface areas of the materials increase and the surfaces get more hydrophobic.Particularly,the specific surface area of magnesium oxide modified by 0.2 mL OTES is as high as 210.1 m^(2)/g.The surface modification of magnesium oxide by OTES greatly improves the CO_(2) adsorption performance of the materials.The CO_(2) adsorption capacity of magnesium oxide modified by 0.1 mL OTES reaches 69 mg_(CO_(2))/g at 200℃,which is 3.1 times larger than that of pure magnesium oxide.
