•We studied the adsorption of MeOH and EtOH on the surface of PtG.•Increasing in the stability of PtG upon complexation with MeOH and EtOH.•Significant shift in the location of both the HOMO and LUMO of system upon complexation.
The adsorption energies and orientation of single alcohol molecule (methanol and ethanol) on the surface of Pt-decorated graphene (PtG) were determined from first-principles density functional (DFT) calculations. We found the same adsorption energies as well as connecting distances upon adsorption of MeOH and EtOH on PtG surface, in which at their relaxed structures, the O atom of alcohol is closed to the Pt of PtG surface. We found high adsorption energies, low connecting distances, and high orbital hybridizing upon adsorption of EtOH and MeOH molecules on PtG surface. There are significant shifts in the location of both the HOMO and LUMO, in addition to variation in the charge transfer when the MeOH and EtOH are adsorbed on PtG surface.
