a Pore size distribution of LDH, MWCNT, and LDH/MWCNT nanocomposites. The calculation was performed on the desorption branch using the Barrett, Joyner, and Halenda method. b XRD pattern of LDH and LDH/MWCNT nanocomposites. The scanning is conducted at ambient temperature via Cu Kα diffractor (λ = 0.154 nm). c CO2 adsorption per unit mass of LDH and LDH/MWCNT nanocomposites as a function of MWCNT content at 300 °C and 0.2 bar of CO2. a–c are reprinted with permission from ref. 42, Copyright 2012 The Royal Society of Chemistry. d Comparison of CO2 adsorption capacity of LDH:OCNT nanocomposites with variation of the LDH:OCNT ratio at 200 °C and 1 bar. The data in this graph were extracted from ref. 39. e Comparison of CO2 adsorption kinetics (for the first cycle) of LDH with GO:MWCNT (1:1) substrate at 300 °C and 0.2 bar. e is reprinted with permission from ref. 41, Copyright 2017 Elsevier. f Measurement of repetitive CO2 adsorption–desorption cycling of γ-Al2O3/RGO/PEI-25 and γ-Al2O3/PEI-25 at 75 °C and 0.15 bar. f is reprinted with permission from ref. 88, Copyright 2016 Wiley-VCH Verlag GmbH & Co.
