Multiammonium surfactants enable novel zeolite nanostructures like nanoparticles, nanorods, and nanosponges. Zeolite nanorods show improved catalytic performance in cumene synthesis.

Area of Science:

  • Materials Science
  • Catalysis
  • Nanotechnology

Background:

  • Zeolite synthesis often relies on surfactants for structure control.
  • Conventional surfactants can be ineffective for creating specific zeolite nanostructures.
  • Developing new templating agents is crucial for advanced zeolite materials.

Purpose of the Study:
