金属氧化物催化剂的活性和表面羟基的含量及金属氧化物的晶型有很大的关系。近红外光谱不仅能定量地确定羟基的含量从而分析酸、碱催化剂的活性与羟基含量的关系,还能通过羟基伸缩振动吸收峰频率的差别区别金属氢氧化物和金属氧化物的不同晶型。
The activity of the metal oxide catalyst is strongly related to the amount of surface hydroxyl groups and the crystalline form of the metal oxide. Near infrared spectroscopy can not only quantitatively determine the hydroxyl content in order to analyze the acid and alkali catalyst activity and hydroxyl content of the relationship between hydroxyl stretching vibration absorption peak frequency difference can be distinguished between different forms of metal hydroxide and metal oxide.
