Abstract EN
Nonequilibrium molecular dynamics simulations are employed to study the adsorption and blockage properties of a 3D graphene membrane.
Specifically, we are interested in the mixtures of carbon dioxide (CO2) and sulfur dioxide (SO2), two of the most relevant pollutant gases for the anthropogenic effect in global warming.
We simulate cases with distinct proportion of gases in the mixture.
Our results indicate that the 3D graphene slit is able to absorb 90% or more of the gas molecules.
We show that this property came from the fact that both CO2 and SO2 molecules are attracted by the graphene pore, which compensates for the entropic barrier that exists when leaving the bulk state to the confined state.
Also, the simulation results show that changing the interlayer separation between the graphene sheets is possible in order to change the membrane properties, from absorbent to blockage.
These results help to understand the properties of 3D graphene nanoslits and their application as highly selective filters.
