原位红外光谱对催化剂表面吸附行为的表征

Functions of in-situ FTIR and the catalyst surface adsorption behavior

采用原位红外光谱,利用CO和NO作为探针分子对催化剂结构进行表征,可以获得丰富的催化剂表面结构信息;利用CH4和NH3作为探针分子对催化剂结构进行表征,可以得到催化剂表面酸性的信息,同时也可表征固体催化剂的性质.

The information of the surface structure of catalyst is attained when the structure of catalyst is mensurated by in-situ FTIR with CO and NO as probe molecules. In the same way, the in formation of the surface acidity of the catalyst is attained with CH4 and NH3 as probe molecules. Hence, the character of solid catalyst is mensurated.
