| 英文摘要 | layered rub-36 and prefer (lamellar precursor of ferrierite) are the precursors of cdo and fer-type zeolites, respectively. both are composed of the same ferrierite (fer) layer building blocks. topotactic conversion from rub-36 to pure silica zeolite zsm-35 has been demonstrated in the presence of a surfactant cetyltrimethylammonium hydroxide (ctaoh). the transformation mechanism of this process was revealed, for the first time, by the detailed investigations of powder x-ray diffraction (xrd), scanning electron microscopy (sem), thermal analysis, and one- and two-dimensional (2-d) solid-state magic-angle spinning nuclear magnetic resonance (mas nmr) as well as theoretical simulations. during swelling at room temperature, cetyltrimethylammonium cations (cta(+)) replacing the original template were intercalated into fer layers to expand the interlayer distance remarkably and consequently to destroy the strong hydrogen-bonding interactions between the layers. 2-d h-1-si-29 heteronuclear correlation (hetcor) nmr indicates that the surfactant polar heads approximate the fer layers in swollen rub-36. after deswelling, only a small amount of cta(+) cations with long tails lay in the void space between the fer layers. the monte carlo simulations on the deswollen rub-36 further elucidate the occlusion of cta(+) cations in the pre-10 member ring of the layered ferrierite precursor, which may act as the structure-directing agent for the formation of fer-structured zeolite. the fer layer reassembly from the alteration of cta(+) conformation at the interlayers is of key importance to the topotactic transformation of rub-36 to fer-type zeolite by the dehydration-condensation reaction. this may open up more applications in the lamellar zeolite system by the layer restacking approach. |
