Synthesis of Mesostructured Materials Using Nb-containing Layered Perovskites and Cationic Surfactants

抄録

Mesostructured composites of layered perovskites and cationic surfactants were synthesized. Layeredperovskite HC_a2Nb₃O₁₀ and alkyltrimethylammonium (C_nTMA) or alkylpridinium (C_nPy) surfactantsformed lamellar-type composites. The interlayer spacings of the composites increased with increasing carbonnumber of alkyl group in the surfactants. The spacings were also affected by the Nb: surfactant ratio in thereacting solutions. From comparison between size of molecule and interlayer spacing, it is suggested thattwo types of composites formed, which contain C₁₆Py⁺ ions with mono-or bilayer arrangements.
