以内转换电子穆斯堡尔谱为主要手段,配合X射线衍射和俄歇电子能谱测定以及化学测试,研究了用化学蒸发沉积(CVD)法制备的以玻璃为基体的SnO_2薄膜,证实了薄膜的织构效应(择优取向),以及在界面上的相互作用;研究了添加锑组分后形成的Sn_(1-x)Sb_xO_2非晶薄膜,由四极裂距的分布得出Sn离子周围环境对称性随添加的Sb含量的变化;研究了不同制备方法制得的MoO_3-SnO_2催化剂,穆斯堡尔参数与催化性能具有相对应的关系。
The internal conversion electron Mossbauer spectroscopy as the main means, combined with X-ray diffraction and Auger electron spectroscopy determination and chemical testing, studied by chemical vapor deposition (CVD) prepared glass-based SnO_2 film, confirmed that the film (Preferential orientation) and the interaction at the interface were investigated. The Sn_ (1-x) Sb_xO_2 amorphous thin films formed by adding antimony were studied. The Sn ions environment Symmetry with the addition of Sb content changes; study of different preparation methods MoO_3-SnO_2 catalyst, Mossbauer parameters and catalytic properties have a corresponding relationship.
