应用原位Mossbauer谱系统地考察了制备方法、锡组分数量、反应气氛及其它组分对铂锡/氧化铝催化剂中锡组分存在状态的影响,获得了锡组分在各种条件下存在状态的清晰图像,从而合理解释了催化剂的反应行为,为催化剂制备及改进提供了依据。
In situ Mossbauer spectroscopy systemically investigated the preparation method, the amount of tin components, the reaction atmosphere and other components on the presence of tin components in the platinum-tin / alumina catalyst status, tin components obtained under various conditions exist Clear state of the image, so as to reasonably explain the reaction behavior of the catalyst for the preparation of the catalyst and provide a basis for improvement.
