2010/4/8
An ultra-sensitive and highly selective non-extractive spectrophotometric method is presented for the rapid determination of iron(II) at trace levels using 2', 3, 4', 5, 7-Pentahydroxyflavone (morin) ...
铁、氮共掺杂二氧化钛粉末的制备及光催化活性（Preparation and Photocatalytic Activity of TiO2 Powder Codoped with Iron and Nitrogen）
二氧化钛 铁 氮共掺杂 亚甲基蓝 光催化
2010/8/18
Using TiCl4 as the titanium source, nanoparticles of TiO2 doped with nitrogen(N-TiO2) were synthesized by triethylamine. TiO2 powder codoped with iron and nitrogen(Fe/N-TiO2) were prepared by adsorpti...
HY沸石超笼“半三明治”环戊二烯铁物种的接枝(Grafting of “Half-sandwich” Cyclopentadiene Iron Species into HY Supercage)
HY沸石 Cp2Fe 接枝反应 半三明治 环戊二烯铁
2010/8/25
在真空条件下研究了Cp2Fe在HY沸石表面的接枝反应，并用原位FTIR、ICP、XRD、TPD-MS和UV-Vis DRS等方法对接枝产物的组成、结构及性质进行了表征。结果表明，在低于423 K的温度下，Cp2Fe可以强吸附在沸石的超笼内，并被氧化为Cp2Fe+阳离子；当在423 K长时间加热时，Cp2Fe+可与超笼表面的酸性中心发生化学反应，脱除一个环戊二烯基团，在沸石超笼形成“半三明治”环戊二...
