Decreasing particle size results in larger increase of external surface area and shorter diffusion path, both reducing mass and heat transfer resistances in catalysis and sorption. A rapid high-temperature hydrothermal synthesis method was developed to synthesize uniform nanoparticles of SAPO-34 zeolite with high crystallinity. To investigate the effects of temperature and synthesis time on purity and crystallinity of the final products, the crystallization temperature was increased from 468 to 673 K while the synthesis time was decreased from 24 h to 45 min. The products were characterized by XRD and SEM techniques. It was found that high temperature and short synthesis time reduce the particle size and change the morphology of the SAPO-34 final product.
Characterization of high-temperature synthesized SAPO-34 products shows that high temperature and short synthesis time reduce the particle size and change the morphology of the SAPO-34 final product.Figure optionsDownload as PowerPoint slide
