摘要
用一种简便快速方法合成了一系列长链有机胺插层V2O5化合物.用粉末X射线衍射(XRD)、红外光谱(FT-IR)、漫反射紫外-可见光谱(DRUV-VIS)等手段对插层产品的结构进行了表征.除了正十六胺插层V2O5产品外,其它长链烷胺插层V2O5产品的层间距d001与长链烷胺碳数n之间具有良好的线性关系:d001=0.160nC+0.731nm.正十六胺与V2O5反应后生成两个插层相,一个相的层间距d001为4.01nm,另一相的d001为3.20nm.此外,研究了手性钛的螯合物Ti[(OC2H4)3N][OCH(CH3)2](记为TEAIP)在V2O5层间的插层行为,得到相应的插层产品.
A series of long-chain n-alkylamine-intercalated layered V2O5 materials were synthesized through a simple and quick route. X-ray diffraction （XRD）, framework FT-IR and diffuse reflectance UV-visible spectroscopy （DR UV-Vis） were employed to investigate the structure of the obtained products. An excellent linear relationship between the basal interlayer distances of the n-alkylamine-intercalated V2O5 and the number of carbon atoms in the n-alkyl chain （d001=0.160nc＋0.731 nm） with an exception for n-hexadecanamine was presented, n-Hexadecanamine-intercalated V2O5 was composed of two guest-intercalated layered phases, and the basal interlayer distances （d00l） of the two phases were 4.01 and 3.20 nm, respectively. The intercalation behavior of titanium（IV） （triethanolaminato）-isopropoxide （TEAIP） in layered V2O5 was also investigated, and the TEAIP intercalated layered V2O5 product was obtained.
