Solvent-free synthesis of SAPO-5 zeolite with plate-like morphology in the presence of surfactants

SAPO-5 crystals with plate-like morphology were synthesized in the presence of surfactants such as cetyltrimethyl ammonium bromide under solvent-free conditions. X-ray diffraction patterns and scanning electron microscopy images revealed that the samples had high crystallinity and controllable plate-like morphology. The amount of surfactant added played an important role in controlling the thickness of the zeolite crystals. Considering the unique one-dimensional microporous architecture of AFI, SAPO-5 crystals with unique plate-like morphology are expected to be of great importance in catalytic applications.
