Nano -magnesium oxide is a material with good catalytic activity and stability. Its application in catalysts is mainly reflected in the following aspects:
As a catalyst carrier
Nano -magnesium oxide has a large ratio of surface area, which can effectively load other catalytic active substances and improve the activity and selectivity of catalysts. For example, nano -magnesium oxide can be used as a carrier of precious metal catalysts such as tadpoles, platinum, and 铑, and is used to catalyze the hydrogenation of olefin and the cracking of the alkane.
As a catalyst activity ingredient
Nano -magnesium oxide itself also has certain catalytic activity and can be used to catalyze some specific reactions. For example, nano -magnesium oxide can be used to catalyze the reaction of carbon monoxide and hydrogen, and generate methane; it can also be used to catalyze the reaction of water and carbon dioxide, and generate methanol.
As a catalyst modifier
Magnesium oxide can be used to modify the performance of other catalysts and improve its activity, selectivity and stability. For example, nano -magnesium oxide can be used to modify acidic catalysts and improve its selectivity to olefins; it can also be used to modify alkaline catalysts and improve its activity to alk.
The application of nano -magnesium oxide in catalysts has the following advantages:
It has a large ratio area and can effectively load other catalytic active substances to improve the activity and selectivity of catalysts.
It has good chemical stability and still has good catalytic activity under high temperature and high pressure.
It has high thermal stability, can be reused to reduce the cost of catalyst.
Therefore, nano -magnesium oxide has broad application prospects in the field of catalysts.
