The CO2 adsorption on the magnetite Fe3O4{001} and {111} surfaces has been studied using density functional theory (DFT) calculations. The Fe ions of Fe3O4 have a mixed valence state (2+/3+), which allows this material to catalyse both oxidation/reduction and acid/base reactions. The work involved studying the charge transfers from the major Fe3O4 surfaces to the CO2 molecule. The data described here are ASCII files containing the charges of the atoms of the CO2 molecule and the topmost layer of the Fe3O4{001} and {111} surfaces before and after adsorption. Calculations were carried out using the Vienna Ab-initio Simulation Package (VASP).

Research results based upon these data are published at https://doi.org/10.1098/rsta.2017.0065
