and Pt-H2O interactions by the PBE functional compared to RPBE evidenced in our study is reconcilable with the observation of Tongold and Groß. This trend is followed by their semiempirical dispersion analogs as well. Furthermore, the deviations in hydrogen bonding energy between the methods are less than Pt-H2O binding energy, which is evident from the differences in treating the metal-H2O weak interaction.
