Synthesis of Novel Scandium Phosphate Microporous
Topologies

• Zeolite
• Family of aluminosilicates materials with a
  porous structure.
• Used as adsorbents, shape selective catalysts,
  and ion exchangers.
• Goal of Synthesis
• New topologies for varied and improved shape
  selective catalysis and ion exchange.

Scandium Phosphate Zeolite Structures

• 4 T 0.5Sc2O3 1.5H3PO4 0.5 HF 80 H2O
• Problems occur with acid pH. This gives dangling
  hydroxides in pore space.
• Methods for Synthesis
• Raise pH to alkaline levels (10-12).
• Vary time and temperature for reactions.
• Vary template chain length.
