纺锤形β-FeOOH的形成过程研究

Submicron spindle and pseudocube α-Fe2O3 particles were synthesized at pH=6～9 in the presence of trace Na2SiO3.

以Ferrihydrite(又称水合氧化铁hydrous iron oxide)为反应前驱物,Fe(II)为催化剂,在微量Na2SiO3存在下,控制pH=6～9范围内合成出了亚微米级纺锤形和准立方形α-Fe2O3微粒。

This dissertation reported the preparation of triangular silver, trangular gold nanoplates, spindle silver, gold and gold-silver bimetallic nanoshells by using a.

本论文采用液相化学还原法和表面种子诱导法，分别制备出三角形银、三角形金纳米片和纺锤形银、金和金银双金属纳米壳层，借助于透射电镜(TEM)、扫描电镜(SEM)、X射线衍射(XRD)、紫外可见吸收光谱(UV-Vis)、拉曼光谱(RS)等现代测试技术对金银纳米颗粒及其纳米壳层的尺度、形状、结构特点、光学特性及其形成机理进行了较为系统的研究。

These structures are similiar to Netropsin’s.

根据纺锤霉素（Ｎｅｔｒｏｐｓｉｎ）的晶体结构及与ＤＮＡ作用方式，我们设计合成了３个含ＳＰＸＸ序列的十肽，它们在空间构象上与纺锤霉素类似。

Homogeneous spindle-shaped γ-FeOOH crystallite were prepared by oxidizing the Fe(CO2)2(OH)2(1-x) suspensions system formed in the solution of FeSO4 and NaWCO3 by doping Y3+.

本文还对γ－ＦｅＯＯＨ的脱水过程机制和以γ－ＦｅＯＯＨ为中间体经热处理制备的纺锤形γ－Ｆｅ２Ｏ３磁性能作了初步探讨。

As spindle-shaped goethite particles are loose,coating them with SiO2, Ni(OH)2 and Co (OH)2 at different hydrothermal temperatures forms a transition layer of a-Fe2O3 ,which makes them compact effectively.

由于纺锤形铁黄粒子较松散的特点，通过在不同水热温度下包覆硅、钴或镍，使纺锤形铁黄脱掉大量凝并接触部分的羟基，形成一层α－Fe2O3过渡层，粒子得到了有效的密实化，从而制备了高性能的纺锤形金属磁粉。
