Atomistic investigation on the diffusion mechanism of Pt nanoclusters on well-aligned multi-walled carbon nanotubes

The equilibrium structure for the 36-Pt1.2/WACNT (4, 4)-(9, 9)-(14, 14) (a) at a 100 ps dynamic time and (b) at a 1 ns dynamic time; the equilibrium structure for 24-Pt2.4/WACNTs (20, 20)-(25, 25) (c) at a 100 ps dynamic time and (d) at a 1 ns dynamic time; the equilibrium structure for 20-Pt3.1/WACNTs (25, 25)-(30, 30) (e) at a 100 ps dynamic time and (f) at a 1 ns dynamic time; the pink dashed lines denote the close distance, and red circles indicate the trend of Pt-cluster aggregation.68
