To correct adsorption energies, we used a simple approach to adjust metal-O(H2O) sigma parameters to reproduce the DFT-calculated binding energies. With the refined parameters, the computed water isotherms inside Mg-MOF-74 and Cu-BTC are in reasonable agreement with experimental data, and provide significant improvement compared to the

resistive gas sensing.

Therefore, it has been suggested for CO2 separations as both an adsorbent and incorporated into membranes. Design of the Mg-MOF-74 crystal morphology is important to expand the applicability of the material. Recent studies explored the capability of zinc-based MOFs, Zn MOF-74 for the removal of As species. Yu et al.
