In addition, in some papers where many MOFs were synthesized, there is no explicit declaration if all the activation process went right or wrong, but rather discussions about gas adsorption characteristics of the successfully activated MOFs were presented, without including the necessary discussions about the collapsed MOFs. Moreover, some papers did not expressively declare the collapse, though, based on the provided experimental characterization results, the failure in activation could be recognized. Here, the absence of XRD peaks was taken as a clear evidence for structure amorphization, if not available then the surface area can be used. But, there were situations where the MOF was described as collapsed in the original experimental paper, but without providing the characterization results, therefore in present study, these cases were considered as collapsed. In contrast, some MOFs were described as activated in the experimental papers without providing sufficient (or any) results to support this claim, yet in present work they were considered as activated.
