Main Results:

  • The pillared structure and high surface area (~350 m2 g-1) were preserved after thermal reduction.
  • TKAM demonstrated stability at reduction temperatures.
  • The resulting porous reduced graphene oxide (PrGO/TKAM) showed reduced hydrophilicity, increased electrical conductivity, and an interlayer distance of ~12 Å.
  • Nitrogen sorption analysis revealed a narrow pore size distribution with a peak at ~7 Å.

Conclusions:

  • TKAM is a suitable organic pillar for creating stable porous rGO.
  • PrGO/TKAM exhibits desirable properties for separation technologies.
  • The material's well-defined hydrophobic slit pores make it promising for membrane and molecular sieve applications.
