The ITQ-37 mesoporous chiral zeolite 被引频次: 147 (来自 Web of Science) 引用的参考文献: 27 [ 查看 Related Records ] 引证关系图引证关系图 摘要: The synthesis of crystalline molecular sieves with pore dimensions that fill the gap between microporous and mesoporous materials is a matter of fundamental and industrial interest(1-3). The preparation of zeolitic materials with extralarge pores and chiral frameworks would permit many new applications. Two important steps in this direction include the synthesis(4) of ITQ-33, a stable zeolite with 18 x 10 x 10 ring windows, and the synthesis(5) of SU-32, which has an intrinsically chiral zeolite structure and where each crystal exhibits only one handedness. Here we present a germanosilicate zeolite (ITQ-37) with extralarge 30-ring windows. Its structure was determined by combining selected area electron diffraction ( SAED) and powder X-ray diffraction (PXRD) in a charge-flipping algorithm(6). The framework follows the SrSi(2) (srs) minimal net(7) and forms two unique cavities, each of which is connected to three other cavities to form a gyroidal channel system. These cavities comprise the enantiomorphous srs net of the framework. ITQ-37 is the first chiral zeolite with one single gyroidal channel. It has the lowest framework density (10.3 T atoms per 1,000 angstrom(3)) of all existing 4-coordinated crystalline oxide frameworks, and the pore volume of the corresponding silica polymorph would be 0.38 cm(3) g(-1). |

Micro/mesoporous composites based on colloidal zeolite grown in mesoporous matrix 被引频次: 8 (来自 Web of Science) 引用的参考文献: 28 [ 查看 Related Records ] 引证关系图引证关系图 摘要: Composite materials containing micro- and mesopores are prepared under instantaneous hydrothermal treatment of initial solutions generally used for zeolite Beta and precursor solutions for mesoporous Al-MCM-41 material. The resulting composites are compared with pure, highly crystalline colloidal microporous Beta zeolite and hexagonally ordered mesostructured samples. The porosity and morphological features of the composite materials are influenced by the conditions of hydrothermal synthesis of the initial colloidal solutions used for the preparation of Beta seeds, as well as by the conditions of the synchronized crystallization of the final composites. The embedding of Beta seeds in the mesoporous silica matrix is possible via immediate heating of mesoporous precursor solutions with Beta seeds primarily formed. The composite materials contain either microcrystalline Beta nanodomains with sizes of about 5 - 10 nm surrounded by mesoporous material or defined Beta nanocrystals ( 20 - 40 nm), and at the same time connected with mesostructured material. The presence of highly crosslinked silicate framework walls and tetrahedrally coordinated aluminum in the composite material are confirmed by solid-state Si-29 and Al-27 MAS NMR spectroscopy.

Mesoporous zeolite materials 作者: Wang, DJ (Wang Deju)[ 1 ] ; Liu, ZN (Liu Zhongneng)[ 1 ] ; Li, XL (Li Xueli)[ 1 ] ; Xie, ZK (Xie Zoiku)[ 1 ] 来源出版物: PROGRESS IN CHEMISTRY 卷: 20 期: 5 页: 637-643 出版年: MAY 2008 被引频次: 3 (来自 Web of Science) 引用的参考文献: 54 [ 查看 Related Records ] 引证关系图引证关系图 摘要: Mesoporous zeolite materials, which are defined as the crystalline zeolite materials containing a large amount of mesopores, not only inherit excellent acidity and hydrothermal stability of zeolite, but also improve the adsorption and diffusion of large molecules due to the insertion of mesopores. Mesoporous zeolite materials have much effective and promised applications in catalysis, especially catalytic reaction involving large molecules. In this article we summarize several methods for the preparation of mesoporous zeolite materials and show their differences. Recent applications of mesoporous zeolite materials in different catalytic reactions are introduced and further research areas of mesoporous zeolite materials are discussed. 入藏号: WOS:000256204100003 |

Templating mesoporous zeolites 作者: Egeblad, K (Egeblad, Kresten)[ 1 ] ; Christensen, CH (Christensen, Christina H.)[ 2 ] ; Kustova, M (Kustova, Marina)[ 1,2 ] ; Christensen, CH (Christensen, Claus H.)[ 1 ] 来源出版物: CHEMISTRY OF MATERIALS 卷: 20 期: 3 页: 946-960 DOI: 10.1021/cm702224p 出版年: FEB 12 2008 被引频次: 211 (来自 Web of Science) 引用的参考文献: 184 [ 查看 Related Records ] 引证关系图引证关系图 摘要: The application of templating methods to produce zeolite materials with hierarchical bi- or trimodal pore size distributions is reviewed with emphasis on mesoporous materials. Hierarchical zeolite materials are categorized into three distinctly different types of materials: hierarchical zeolite crystals, nanosized zeolite crystals, and supported zeolite crystals. For the pure zeolite materials in the first two categories, the additional meso- or macroporosity can be classified as being either intracrystalline or intercrystalline, whereas for supported zeolite materials, the additional porosity originates almost exclusively from the support material. The methods for introducing mesopores into zeolite materials are discussed and categorized. In general, mesopores can be templated in zeolite materials by use of solid templating, supramolecular templating, or indirect templating. In this categorization of templating methods, the nature of the interface between the zeolite crystal and the mesopore exactly when the mesopore starts to form is emphasized. In solid templating, the zeolite crystal is in intimate contact with a solid material that is being removed to produce the mesoporosity. Similarly, in supramolecular templating, the zeolite crystal is in direct contact with a supramolecular assembly of organized surfactants, which is removed to generate the mesopores. On the other hand, in the indirect templating method, the interface is between the zeolite crystal and solvent molecules, or possibly a gas phase. It is shown that the available templating approaches are quite versatile, and accordingly, it is possible to produce a very wide range of hierarchical zeolite materials. The resulting zeolite materials, featuring noncrystallographic mesopores in addition to the crystallographic micropores, exhibit significantly enhanced diffusional properties in comparison with purely microporous zeolite materials. These enhanced mass transport properties have been shown in several cases to result in significantly improved catalytic properties in a range of important reactions. |
