一、绪言人们应用等温吸附线测定表面积或测定吸附热等方法来研究分子与催化剂表面的作用及其机理已有数十年的历史。这些方法被认为是较经典和成熟的方法,但它们有共同的缺陷:即不能直接观察表面力对吸附分子的作用。随着科学技术的发展而广泛地应用起来的红外光谱技术郤能弥补这个缺陷。应用红外光谱于化合物定性定量分析及分子结构分析的历史已很久;而将红外光谱技术应用于表面化
I. INTRODUCTION It has been decades for people to study the effect of molecular and catalyst surfaces and their mechanisms using isothermal adsorption line to determine the surface area or to determine the adsorption heat. These methods are considered to be more classical and mature methods, but they have the common flaw: that can not directly observe the surface force on the adsorption of molecules. With the development of science and technology and widely used infrared spectroscopy technology can make up for this shortcoming. The application of infrared spectroscopy in the qualitative and quantitative analysis of compounds and molecular structure analysis has a long history; and infrared spectroscopy applied to the surface
