| 英文摘要 | A new layered silicogermanate, PKU-22, was hydrothermally synthesized under fluoride conditions using the tetraethylammonium (TEA(+)) cation as the structure directing agent (SDA). The crystal structure was determined by single crystal X-ray diffraction. Structure analysis reveals that PKU-22 is constructed by sti layers stacking along the [100] direction in an center dot center dot center dot AAAA center dot center dot center dot manner, with TEA(+) cations occurring in the interlayer spaces and F- anions residing within the layer and connecting to Ge atoms, which also act as the charge compensation species. In situ temperature-variable powder X-ray diffraction results indicated that PKU-22 could be into a three-dimensional STI-type zeolite PKU-22a on heating. It is interesting that the TEA+ cations remain transferred structure of the condensed product. Solid-state NMR, inductively coupled plasma atomic emission spectroscopy, intact in the thermogravimetric-differential scanning calorimetry, and carbon, hydrogen, and nitrogen elemental analyses were applied to aid the structure analysis of PKU-22 and illustrate its transformation. The scheme of the topotactic condensation of PKU-22 to PKU-22a is proposed. |
