摘要：

A new potassium phosphatoantimonate was hydrothermally synthesized and characterized by means of powder X-ray diffraction (XRD), scanning electron microscopy (SEM), differential thermal analysis (DTA), thermogravimetric analysis (TGA), infrared spectroscopy (IR), P-31 solid-state NMR, and adsorption isothermal analysis. Results showed that this compound has a layered structure with the formula K8Sb8P2O29 . 8H(2)O. It crystallizes in the monoclinic system with unit-cell parameters a = 23.95(2) Angstrom, b = 9.51(5) Angstrom, c = 8.19(3) Angstrom, and beta = 124.77 degrees. The structure can be intercalated by organic amine molecules and the potassium ions located in between layers can be exchanged by monovalent ions. Factors such as the initial Sb/P molar ratio, pH, reaction temperature, and cations which dominate the hydrothermal synthesis of the product were assessed.
