Synthesis and characterization of zeotype ANA framework by hydrothermal reaction of natural clinker.
MetadataShow full item record
AbstractThe zeotype ANA framework was successfully synthesized for the first time by conventional hydrothermal alkaline activation of natural clinker. The synthesis process was investigated as a function of the starting material, reaction temperature, reaction time and mineralizer concentration. The as-synthesized products were characterized by X-ray powder diffraction (XRPD) analysis, scanning electron microscopy (SEM), Fourier transform infrared (FT-IR) spectroscopy, magic-angle spinning nuclear magnetic resonance (MAS NMR) and thermogravimetric analyses (TGA). The results of this study indicate that ANA with a low quantity of impurities can be synthesized using natural clinker as starting material.
