摘要：
With a hydrothermal technique, a layered titanium phosphate with the formula Ti-2(H2PO4)(HPO4)(PO4)(2) . 0.5C(6)N(2)H(16) (denoted TP-J2) has been prepared by treating the Ti/H3PO4/H2O/1-methylpiperazine system directly. The as-synthesized products were characterized by powder X-ray diffraction, CP-MAS solid-state P-31 NMR spectroscopy, thermogravimetric and differential thermal analyses (TG-DTA). The structure was solved by single-crystal X-ray diffraction analysis and it presents an extended gamma-phase intercalated with organic amine. Crystal data: triclinic, P (1) over bar a = 8.106 (2) Angstrom, b = 8.197 (2) Angstrom, c = 11.658 (2) Angstrom. alpha = 78.32 (3)degrees, beta = 80.85 (3), gamma = 77.90 (3)degrees, Z = 2. Additionally, the intercalation behavior of TP-J2 with n-alkyl monoamine (n = 2, 3, 4, 6, 8, 10 and 12) was investigated. Owing to the strong bronsted base, N,N'-dimethylpiperazine, resides in the interlayer, it presented unusual features of TP-J2 in contrast with that of gamma-Tip. (C) 2004 Elsevier Ltd.
