| 英文摘要 | An aluminum-free zinc-bearing smectite (Zn-smectite) was synthesized under hydrothermal conditions, together with its magnesium substituted products. Its layer charge calculated by cation exchange capacity (CEC) is 117.4 mmol/100 g. Powder X-ray diffraction (XRD) revealed turbostratic stacking and showed that the d(06l) value of the Zn-smectite was >1.525 angstrom, indicating that it is trioctahedral. Its d(001) value increased from ca.12.8 angstrom to ca. 16.0 A after ethylene glycol (EG) saturation. The Zn-smectite did not irreversibly collapse after heating the Li+-saturated sample to 300 degrees C, suggesting that its layer charge was generated from octahedral-site vacancies (defects). The Zn-smectite resembles zincsilitelike minerals with interlayer Na+ and Zn2+. The intralayer structure of zincsilite was confirmed by pair distribution function (PDF) analysis, and the whole crystal structure was built and optimized by DFT calculation in the CASTEP module of the Materials Studio software. Synthetic zincsilite is triclinic, space group P1, and its optimized unit-cell parameters are: a = 5.294 angstrom, b = 9.162 angstrom, c = 12.800 angstrom, alpha = 90.788 degrees, beta = 98.345 degrees, and gamma = 90.399 degrees. |
