Beschreibung
Zusammenfassung:	The invention provides a synthetic method for TiSiCeOx catalytic materials with adjustable specific surface areas, which belongs to the technical field of oxide catalysts. According to the invention, polyethylene glycol (PEG) is used as a dispersant, TiSiCeOx materials with different Ti/Si ratios are prepared by using a hydrolysis method, and the specific surface areas of the materials can be realized by adjusting feeding ratios of Ti/Si; pore size distribution of the materials is narrow. According to the invention, raw materials are cheap and easily available, preparation process is simple, preparation conditions are easily controllable, product morphology and size are controllable, and the prepared TiSiCeOx materials have certain NH3-SCR catalytic activity and N2 selectivity.
