Adsorption and desorption studies of CO2 (a) and fluorocarbon dichlorodifluoromethane (R12) (b) in Ni-MOF-74(DGC) and Ni-MOF-74(CS). Note that there are improved sorption capacities in both CO2 and R12 sorption measurements. For clarity, R12 sorption capacities are presented in a zoomed-in scale to see the improved performance more clearly (inset).
