一、前言近30年来,由于光谱技术的发展,使物理和化学家们获得了丰富的表面及表面吸附物种结构方面的信息,这些微观信息对深入了解催化和腐蚀机理以及发展新材料起了很大作用。光谱技术的重点是红外和激光拉曼光谱,它们在分析和催化研究中获得了广泛的应用,尤其在研究材料体相中原子和分子振动模式是很有用的。但是用在研究表面上吸附物种时信号较弱,以致检测不到,另外,利用透射红外研究载体催化剂时,由于部分载体在低于1000cm~(-1)不透明,很难获得这一波数以下的
I. INTRODUCTION In the last 30 years, due to the development of spectroscopic techniques, physicists and chemists have gained a wealth of surface and surface-adsorbed species-structure information that has been instrumental in gaining insight into catalytic and erosion mechanisms and the development of new materials Great effect. The focus of spectroscopy is infrared and laser Raman spectroscopy, which have gained widespread use in analytical and catalytic studies, and are particularly useful in the study of atomic and molecular vibration modes in bulk. However, the signal is weaker when it is used to study the adsorption species on the surface and can not be detected. In addition, when the carrier catalyst is studied by transmission infrared, it is very difficult to obtain the carrier below opaque at some carrier below 1000 cm -1
