When multiple characterization isotherms for a given adsorbent are available from the same paper, it is tempting to attribute these differences to experimental uncertainty or inaccuracies of the digitization. However, inspection of some of these articles reveals that in most cases such isotherms are used for the characterization of different synthesis or activation attempts, and the isotherm with the maximum pore volume typically corresponds to the optimal procedure. We acknowledge that the maximum pore volume does not unequivocally imply optimal crystallinity -for example, the presence of defects can also lead to higher pore volumes -however, recognizing such cases goes beyond the scope of our automated comparison. For the sake of consistency, in cases of multiple isotherms, we therefore selected the one giving the maximum pore volume and discarded all others from the same article.
