中文摘要:

在温和状况下面的一个灵巧的受精方法在做氮的碳 nanotubes (CN x ) 上与 47 nm 的一种狭窄的尺寸为高度驱散的磅 nanoparticles 的合成被设计。CN x 不需要任何东西预先出现修正由于固有的化学活动。Pt/CN x 的结构和自然被 X 光检查衍射描绘,扫描电子显微镜学,传播电子显微镜学和精力散光谱学光谱。所有试验性的结果表明在 CN x 的大量做的氮原子为捕获磅(IV ) 是几乎有效的离子。改进表面氮功能和 hydrophilicity 在 CN x 表面上贡献了磅 nanoparticles 的好分散和固定。Pt/CN x 在 allyl 酒精的加氢用作活跃、可重用的催化剂。这能被归因于在磅和支持之间的磅 nanoparticles 和更强壮的相互作用的高分散,它阻止了磅 nanoparticles 聚集进不太活跃的磅黑色并且从也沥滤。

英文摘要:

A facile impregnation method under mild condition is designed for synthesis of highly dispersed Pt nanoparticles with a narrow size of 4-7 nm on nitrogen-doped carbon nanotubes (CNx). CNx do not need any pre-surface modification due to the inherent chemical activity. The structure and nature of Pt/CNx were characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy and energy dispersive spectroscopy spectrum. All the experimental results revealed that the large amount of doped nitrogen atoms in CNx was virtually effective for capturing the Pt(IV) ions. The improved surface nitrogen functionalities and hydrophilicity contributed to the good dispersion and immobi- lization of Pt nanoparticles on the CNx surface. The Pt/CNx served as active and reusable catalysts in the hydrogenation of allyl alcohol. This could be attributed to high dispersion of Pt nanoparticles and stronger interaction between Pt and the supports, which prevented the Pt nanoparticles from aggregating into less active Pt black and from leaching as well.
