摘要
红外光谱是催化研究中最重要的工具之一,用于表征催化剂的表面性质.磷酸铝分子筛(APO)作为一类新型的分子筛,本身是中性骨架结构,只有微弱的酸性.通过同晶取代,会出现具有特殊催化性能的新材料.而IR光谱技术能直接用于表征掺杂元素的存在方式,及取代对分子筛酸性质的影响.
The crystalline microporous aluminophosphate (APO) is new molecular sieves, which is a neutral framework and has weak acidity. The other element isomorphous incorporation can improve APO-5 specific property. The IR measure technology is an important means in catalysis, the diffuse reflectance infrared Fouried transform can detect the element forms at framework structure, and investigate the molecular sieves property.
