Fabrication of analcime zeolite fibers by hydrothermal synthesis

Analcime (ANA) zeolite fibers with an average diameter of 300-600 nm were prepared for the first time by means of the in situ TPAOH template electrostatic self-assembly technique. In this paper, the conditions of its formation such as pH of synthesis sol and effect of α-Al2O3 plates have been described in detail. The structure and thermal stability of the fibers have been confirmed by means of XRD, FT-IR, and DTA analyses. The surface morphology, size distribution, and elemental composition of ANA nanoparticles have been characterized by HRTEM and SEM-EDX approaches.
