Correspondence on “The Open DAC 2023 Dataset and Challenges for Sorbent Discovery in Direct Air Capture”

This Correspondence provides a brief commentary on a recent ACS Central Science article that identifies metal− organic frameworks for direct air capture and suggests that the recommended structures are artifacts of the methodology used. T he recent article Sriram et al. 1 carried out a detailed screening of metal−organic frameworks (MOFs) for direct air capture (DAC). In this work, a promising material was defined as one with a binding energy of CO 2 that is sufficiently large (i.e., E bind CO 2 > 50 kJ mol −1) and larger than
