Description

We use density functional theory to examine the dissociative adsorption of water (HO-H), hydrochloric acid (H-Cl), methanol (CH3O-H), methyl acetate (CH3O-COCH3) in acceptor/donor fragments on band gap oxides. The ASE database linked here contains all the investigated structures in ASE format. We also provide the script that have been used to calculate the PBE energies and the one that generates the plot for the interaction energy versus the band gap of the clean surface.

Interaction Energy vs Band Gap

The script available here plots the interaction energy as a function of the band gap of the clean surface.
