Study on the Formation Process of Spindle β-FeOOH Particles;
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。
