摘要: Hybrid adsorbents for CO2 capture were prepared by coassembling laponite (LP) nanosheets and 1-n-butyl-3-methylimidazolium chloride (BMIMCl). The prepared BMIMCl/LP layered hybrids were systematically characterized. The interlayer distance of the BMIMCl/LP layered hybrids expanded with an increasing concentration of BMIMCl, indicating that cumulative BMIMCl was intercalated into the LP layers. The efficiency of BMIMCl toward CO2 capture was significantly enhanced after it was immobilized within LP layers.
