Crystal structure of the zeolite mutinaite, the natural analog of ZSM-5 We describe the crystal structure of the high-silica zeolite mutinaite, recently found at Mt. Adamson (Northern Victoria Land, Antarctica). Mutinaite is the natural counterpart of the synthetic zeolite ZSM-5. The new ...
Zeolite with a structural feature as small as the size of a unit cell (5–10nm) with hierarchically ordered porous structure would be very promising for catalysis. 展开 关键词: mesoporous materials nanostructures solid acid catalysts structure‐directing agents zeolites ...
High structure-directing activity and specificity of templating action of tetrapropylammonium cations TPA+ as well as high concentration of framework-forming substances in the initial reaction mixtures contribute to the formation of zeolite ZSM-5 at relatively low temperature (100 °C) in the alkali...
