纳米TiO2/蛋白土复合材料的制备及其表征

Formaldehyde was very harmful to human body,it could be degraded into water and carbon dioxide,the complex of nano-TiO2 and opal would resovle the problem of forthputting and inconvenient recycling. Nano-TiO2/Opal Composite was prepared by the method of hydrolyzation-precipitation with opal as carrier, TiCl4 as precursor. The composite was characterized by SEM, XRD and TEM. The results showed that Nanoscale TiO2 was loaded to the surface of opal particles, and its crystal was anatase type. The degradation rate of formaldehyde could be more than 90% by using this composite.
