For the set of dc-XC functionals studied here, the already identified trends could provide some indications for future studies, potentially allowing to discard some of the functionals and consider other, more promising ones instead. Second, further work should include temperature effects, and potentially also consider the choice of an appropriate reference state that would ultimately allow the prediction of adsorption enthalpies for species adsorbed from aqueous solution. Third, adsorption-induced deformations of the zeolite framework should be accounted for. Finally, protonated or cation-exchanged zeolites can be more attractive than all-silica zeolites for some applications involving the adsorption of functional organic molecules. Future DFT studies of these systems, which have a more heterogeneous charge distribution, would require further validation. As it is well known that the PBE-D3 functional exhibits systematic errors for cationic zeolites, it would be very interesting to evaluate whether rev-vdW-DF2 performs better for these materials.
