摘要Layered inorganic-organic TiO2-ILs hybrids with tunable basal spacing were fabricated through electrostatic interaction between 2D inorganic nanosheets and organic imidazolium-based ILs. Imidazolium cations with various sizes were intercalated into lamellar titanate nanosheets, forming layered structures with slabs turbostratic restacking. The effects of cation sizes on the interfacial properties of hybrids were comprehensively investigated by XRD, SEM, TEM, AFM, FT-IR, Raman and TG techniques. The results confirmed that the ratio of interlayer imidazolium cations declined with increasing carbon chain length. A CO2 absorption experiment was conducted and TiO2-ILs compounds displayed enhanced CO2 absorption capacity with the increase of alkyl chain length, which could be attributed to the synergistic interfacial effects induced by diverse interactions between ILs and inorganic nanosheets. An absorption mechanism was proposed on account of ion-exchangeable characteristic of these layered hybrids and the intercalated H2O molecules were found to play a crucial role in CO2 uptake.
