摘要：

Using butyl titanate, silver nitrate, tired rectorite (REC) as raw materials, titanium dioxide (TiO2) and silver (Ag) were loaded onto the octahedron structure of the tired rectorite by Sol-Gel method, and REC- TiO2 and REC- TiO2 -Ag Composites were successfully prepared. The Photocatalytic properties and adsorption properties were also studied. The results showed that the adsorption rate of REC-TiO2-Ag to methylene blue was higher than that of REC- TiO2. In the same proportion of REC- TiO2 -Ag and REC-TiO2 Composites, REC-TiO2-Ag composites have better adsorption effect on methylene blue, and the balanced adsorption of REC-TiO2-Ag composites at 25 degrees C is 54.054 mg/g. The equilibrium adsorption amount of REC-TiO2 composites is 36.49 mg/g. At the same time, the photocatalytic degradation rate of REC- TiO2 -Ag to methylene blue was 96%, which was significantly higher than that of REC-TiO2.
