CO₂ has been found to be the main anthropogenic contributor to the greenhouse gas effect, thus, the development of carbon capture and storage (CCS) technology is extremely urgent. In this work, two kinds of Al₂O₃ pillared montmorillonite, one ZrO₂-pillared montmorillonite and one TiO₂ + SiO₂ pillared montmorillonite were prepared and characterized by X-ray diffraction (XRD) for phase formation and N₂ adsorption–desorption isotherms for surface area and pore-size distribution. Equilibrium adsorption of CO₂ gas was measured at 273 K. CO₂ adsorption capacities of pillared clays increased with the increase of their pore volume. The uptakes of CO₂ by pillared clays were in the range of 0.53–1.18 mmol/g.

几种柱状蒙脱土对CO 2的吸附

已经发现CO ₂是造成温室气体效应的主要人为贡献者，因此，碳捕获和存储（CCS）技术的发展非常迫切。本文制备了两种Al ₂ O ₃柱状蒙脱土，一种ZrO ₂柱状蒙脱土和一种TiO ₂  + SiO ₂柱状蒙脱土，并通过X射线衍射（XRD）表征了相形成和N ₂吸附-脱附。表面积和孔径分布的等温线。在273 K下测量了CO ₂气体的平衡吸附。CO ₂柱状粘土的吸附能力随孔体积的增加而增加。柱状粘土对CO ₂的吸收范围为0.53-1.18 mmol / g。
