DFT/CC investigation of physical adsorption on a graphite (0001) surface

Abstract

The physical adsorption of molecules (C2H2, C2H4, C2H6, C6H6, CH4, H2, H2O, N2, NH3, CO, CO2, Ar) on a graphite substrate has been investigated at the DFT/CC level of theory. The calculated DFT/CC interaction energies were compared with the available experimental data at the zero coverage limit. The differences between the DFT/CC results and experiment are within a few tenths of kJ mol−1 for the most accurate experimental estimates (Ar, H2, N2, CH4) and within 1–2 kJ mol−1 for the other systems (C2H2, C2H4, C2H6, C6H6, CO, CO2). For watergraphite and ammoniagraphite complexes, DFT/CC predicts interaction energies of 13 kJ mol−1 in good accord with the DF-DFT-SAPT and DFT-D calculations. The relevance of the results obtained with the coronene model for the description of the physisorption on graphite surface was also studied.
