Studies on the Hydrothermal Synthesis and Structure of (Ga, Fe, B)-βZeolites

Abstract

Abstract: Aseries of novel M-β zeolites, M=B, Fe, and Ga, were hydrbthermally synthesized.The effects of amounts of Na₂Oand (TEA)₂Oin the initial mixture on the crystallization and crystallite size of Band Fe-β zeolites were investigated.The SiO₂/M₂O₃ ratios and structural characteristics of products were determined by means of chemical analysis, X-fluorescence, X-Ray diffraction, IRspectra, XPSand SEM.The results show that the particle sizes are well distributed and crystallinity ofM-β is considerably high.The binding energy of Fe_{₂F_3/2} electron of ferribeta, IRspectra and unit cellparameters of the resulting M-βzeolies were obviously changed due to the additions of hetero-atoms in the initial mixture.

Key words: M-&beta, zeolites (M=B,Fe,Ga) Hydrothermal synthesis, Unit cell parameters, IR spectra, XPS analysis
