| 英文摘要 | A todorokite-type manganese oxide Molecular sieve material was successfully synthesized at atmospheric pressure by refluxing treatment of Cu(2+) exchanged Na-buserite (named as Cu-OMS-1). TEM (transmission electron microscope) and HRTEM (high resolution transmission electron microscope) images revealed that this material has a needle-phase crystal morphology with thickness 0.1-1 pm, and the lattice fringes spacing 1.0 nm corresponding to the [100] plane of the todorokite structure. Such morphological and intergrowth characteristics were similar to those of hydrothermally synthesized todorokites. The Cu-OMS-1 with a chemical composition of Cu(0.34)MnO(2.19) - 1.11H(2)O, was stable below 400 degrees C. The BET surface area was found to be 62.5 m(2)/g, and a major micropore size distribution peak centered at 0.70 nm for Cu-CMS-1 by the Horvath-Kawazoe (HK) method. As determined by the t-plot method, 31% of the surface area was contributed by micropores. The pH of reaction solution plays an important role in the sub-structure modification of formed Cu-buserites and the formation of todorokite at atmospheric pressure. A mechanism for the influence of pH on the transformation is discussed. (C) 2008 Elsevier Inc. All rights reserved. |
