How Accurate Is DFT for Alkanes and Water Adsorbed in Acidic Zeolites?
We assess the accuracy of electronic structure methods for modeling the dispersion-dominated adsorption of methane, ethane, and propane, and the adsorption of hydrogen-bonded water in the Brønsted acidic zeolite chabazite (H–CHA) using density functional theory (DFT) with periodic boundary conditions and a hybrid QM:...
