WebFeb 17, 2024 · A continuum salvation model (COSMO) with the dielectric constant of water as 78.54 was employed considering the aqueous adsorption. In regard to the effect of weak interactions (such as hydrogen bond and Van der Waals force), the Tkatchenko–Scheffler (TS) method for DFT dispersion correction was also used. WebGeometry and lattice optimizations, as well as vibrational free energies, are computed with the Perdew-Burke-Ernzerhof (PBE) functional in conjunction with the effective-pairwise Tkatchenko-Scheffler (TS) dispersion correction (denoted as PBE + TS) .
