a CO2 adsorption isotherm at 23 °C for HKUST-1, HKUST-1/GO nanocomposites and HKUST-1/aminated GO nanocomposites (MOF/GO-U1, MOF/GO-U2, MOF/GO-U3). a is reprinted with permission from ref. 98, Copyright 2014 Elsevier. b CO2 adsorption at 25 °C of UiO-66 and UiO-66/GO nanocomposites. b is reprinted with permission from ref. 99, Copyright 2015 Elsevier. c N2 physisorption isotherm (77 K) of Mg-MOF-74 [a]; Mg-MOF-74@CNT [b] and Mg-MOF-74@GO [c]. c is reprinted with permission from ref. 21, Copyright 2021 Elsevier. d CO2 adsorption at 25 °C of NiDOBDC and NiDOBDC/GO nanocomposites. d is reprinted with permission from ref. 43, Copyright 2018 Elsevier. e H2 adsorption of selected mixed-dimensional (0D–2D and 3D–2D) nanocomposite, measured at 77 K and >20 bar. The data were extracted from Supplementary Table 2, and the data of homogeneous 3D porous materials were obtained from a study on MOFs101,102. The solid reference line was obtained from the plot of excess gravimetric adsorption capacity vs. surface area of porous carbon, and the dashed line indicates the estimated upper limit of H2 adsorption (where the H2 is adsorbed into a monolayer and has the density of liquid-phase H2)105.
