“…[ 37,39 ] Specifically, MOFs ( Figure ) such as HKUST‐1, NU‐111, NU‐125, UTSA‐20, PCN‐14, Ni‐MOF‐74 (Ni‐CPO‐27), and Co(bdp) are promising for methane storage. [ 22,37,39,94,99 ] In 2014, Long and co‐workers made recommendations for the consistent reporting of methane adsorption data for MOFs: [ 46 ] i) report the background high‐pressure methane adsorption isotherms for the empty sample holder at all measured temperatures and pressures as supplementary information; [ 46,100,101 ] ii) specify whether the isotherms are reported in terms of excess, total, or absolute adsorption; [ 46,101 ] when the experimental excess adsorption data are converted to the total or absolute adsorption, the methods and assumptions should be detailed; [ 46 ] iii) when reporting volumetric uptakes, the density used and the type of density (e.g., crystallographic, [ 34 ] bulk, tap, pellet) should be given; [ 46,102 ] for instance, when crystallographic densities are used, Long and co‐workers recommended reporting details such as the unit cell volume and unit cell content; [ 42 ] iv) define the temperature and pressure before using the unit cm 3 STP ; [ 46 ] v) the method used to calculate the isosteric heats of adsorption should be detailed as well; [ 46 ] vi) in the event where mathematical fitting of experimental adsorption isotherms is performed, all fitted parameters and the quality of the isotherm fits should be reported.
