Research Progress in Design of Composite Catalysts of Mesoporous Silica/Metal Oxides

有序介孔材料具有比表面积高、孔径较大、孔径及孔的形状可调、孔表面易于修饰以及形貌多样可控等优点,是一种良好的载体。研究发现,将金属氧化物负载在介孔材料可以极大地提高金属的催化性能。综述了单金属氧化物催化剂和双金属氧化物催化剂以及双金属催化剂在介孔二氧化硅材料上负载的方法,为之后的发展提供参考。

Ordered mesoporous materials have the advantages of high specific surface area,large pore size,adjustable pore size and shape,easy modification of pore surface,diverse and controllable morphology,etc.,so they are a good carrier.It is found that the catalytic performance of metals can be greatly improved by loading metal oxides on mesoporous materials.In this paper,monometallic oxide catalyst and bimetallic oxide catalyst,as well as bimetallic catalyst loading method on mesoporous silica material were reviewed,providing some reference for future development.
