| 英文摘要 | gallophosphate (gapo4) molecular sieves were ionothermally prepared in 1-alkyl-3-methyl imidazolium bromide ionic liquids (ils) with alkyl chain length varying from 2 to 6 carbons for the first time. three kinds of gapo4 materials such as gapo4-a, cloverite (denoted as clo below) and gapo4-lta were obtained, and their structures and morphologies were characterized by powder and single crystal xrd, sem and multi-nuclear nmr. in the case of 1-ethyl-3-methyl imidazolium bromide ionic liquid, large single crystals of gapo4-lta with well-defined octahedral morphology was obtained in both sealed (ca. 400 mu m in size) and open vessels (ca. 300 mu m in size). ionothermal synthesis is an effective method for the preparation of large single crystal of molecular sieves. with the alkyl chain length of the ionic liquids increasing from 2 carbons to 6 carbons, the size of gapo4-lta decreased sharply. the organic template cations in the as-synthesized gapo4-lta crystals may have two different kinds of conformational structures. fluorine plays a role of co-template along with organic cations of ils in the synthesis of gapo4-lta and clo, while only gapo4-a was obtained in the absence of fluorine. the reaction temperature can also affect the structure of the final structure. in the reaction medium of 1-ethyl-3-methyl imidazolium bromide il, gapo4-lta was obtained at 180 degrees c, while clo was obtained at 150 degrees c. crown copyright (c) 2008 published by elsevier inc. all rights reserved. |
