摘要: 用水热晶化法合成了M-β沸石(M=B,Fe,Ga),讨论了原始反应物料中Na2O和(TEA)2O的含量等因素对(B、Fe)-β沸石合成及晶粒大小的影响。通过化学分析、X荧光分析、XRD、IR、XPS和SEM对样品进行SiO2/M2O3比测定及结构特性表征。结果表明,合成的M-β沸石晶粒均匀、结晶度高。由于杂原子的掺入,引起Fe2F3/2电子结合能、Fe-β红外光谱和晶胞体积明显变化。

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 Fe2F3/2 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
