Surface study of platinum decorated graphene towards adsorption of NH 3 and CH 4

To distinguish the potential of graphene sensors, there is a need to recognize the interaction between graphene sheet and adsorbing molecules. We used density functional theory (DFT) calculations to study the properties of pristine as well as Pt-decorated graphene sheet upon adsorption of NH3 and CH4 on its surface to exploit its potential to be as gas sensors for them. We found much higher adsorption, higher charge transfer, lower...
