Insight into the Structure of Layered Zinc Hydroxide Salts Intercalated with Dodecyl Sulfate Anions

Popis výsledku v původním jazyce

This Article presents the systematic experimental and theoretical investigation of the structural arrangements of dodecyl sulfate (DS) anions in the interlayer space of layered zinc hydroxide salts (LZH-DS) and of the structure of zinc hydroxide layers,with a detailed description of the zinc ions coordination environment. As-prepared, well-crystalline LZH-DS has a basal spacing of 31.5 angstrom. After treatment with methanol at room temperature, zinc hydroxide layers shrank to form two new layered phases with basal spacings of 26.4 and 24.7 angstrom. The shrinking was accompanied by a decrease in the content of DS anions in the interlayer space, indicating a change in the alignment of the intercalated anions and a decrease in the charge density of thezinc hydroxide layers. The latter effect was assessed by the atomic pair distribution function (PDF) analysis of powder X-ray diffraction patterns, revealing the successive removal of Zn ion tetrahedra from the hydroxide layers, with the
