Color key: Gray atoms = graphene; colored clusters = Pt atoms (based on final cluster membership).
Time step: 2 fs; each frame = 2 ps; total simulation ≈ 400 ps.
Process: PVD of Pt on graphene at 300 K; sequential loading from 0.25 to 2.50 ML (1.00 ML = 100% area).
Substrate size: graphene cell ≈ 15 × 14.8 nm².
Initial hydrogen molecules: 1,200 H₂ molecules.
Color key: Red = molecular H₂; blue = atomic H.
Time step: 1 fs; each frame = 2 ps; total simulation ≈ 400 ps.
Temperature: 300 K (room temperature).
Process: MD simulation of H₂ dissociation and chemi-resistive sensing on Pt-functionalized graphene.
