拉曼光谱

有用拉曼光谱表征光催化剂TiO2的吗????
从拉曼光谱中能看出什么信息呢???????????

拉曼给出的是振动信息，而振动光谱很少用来解释光催化现象。光催化中涉及的是电子能级跃迁，用紫外可见光谱表征

nod,raman很少用于光催化剂,最多是用于表征催化剂的结构.

raman太有用了，对振动信息很有说服力，判断价态配位环境很好用，可惜有仪器的地方少

有用，可参考大化所工作，不过人家用的是紫外拉曼，好像国内就他们有，具体可参考文献Jing Zhang and Can Li et al.，J. Phys. Chem. B, 2006, 110, 927.
我们实验室有激光拉曼，拉曼可用于晶体微结构表征，利用变温拉曼研究过TiO2，具体可参考文献

主要还是催化材料的表征！对反应机理的探索可能有帮助。我没做过，可以参考下面一些文献：

这个帖子可是把催化专版里的光催化牛人全吸引来了

Raman可以用于TiO2的结构表征，没有问题的。我做过一点工作，研究TiO2的相变。至于催化性能，可能需要UV-Vis。
