| titleOfInvention |
A kind of preparation method and application of silver/silver halide-loaded mesoporous titanium dioxide microspheres |
| abstract |
The invention provides a method for preparing silver/silver halide-loaded mesoporous titanium dioxide microspheres, comprising: mixing an appropriate amount of tetrabutyl titanate and diethylene glycol, stirring at 25° C. for 8 hours; adding dropwise to acetone and continuously stirring to obtain white precipitate; heat the collected white precipitate at 550°C for 8h to obtain anatase-type titania microspheres; weigh an appropriate amount of titania microspheres and disperse them in 20mL of pure water and stir for 1h, then add an appropriate amount of cetyltrimethyl halide dropwise ammonium and continue to stir for 1 h; add silver nitrate solution and continue to stir for 1-2 h; after 30 min of illumination, centrifuge to collect the precipitate, wash with pure water to obtain the sample; dry the sample at 60 °C, and then heat it in a nitrogen atmosphere at 300 °C After 8 h, silver/silver halide-loaded mesoporous titania microspheres were obtained. The titanium dioxide microspheres prepared by the invention can be used as an effective visible light catalyst for catalyzing the decomposition of formaldehyde. |
