Implication

Randomized trial demonstrates enhanced water permeance in reduced graphene oxide membranes, indicating improved purification efficiency.

Key Points

  • This research aims to improve the permeability-selectivity trade-off in reduced graphene oxide membranes for water treatment.
  • Utilized a defect-excavation strategy with mild KOH etching to create vertical nanopores.
  • Introduced ionic-liquid intercalation for thermodynamic stabilization of the membrane structure.
  • Conducted molecular dynamics simulations to investigate the cooperative transport mechanism.
  • The optimized KOH-IL-rGO membrane achieved a water permeance of 455 L m−2 h−1 bar−1.
  • Exhibited a methylene blue rejection rate of 99.68%.
  • Molecular dynamics simulations revealed enhanced permeability through vertical shortcuts and expanded interlayer spacing.
