Effect of Loading Amount on the Application Performance of Diatomite-Based TiO2 Composites
In order to improve the application performance of diatomite-based TiO2 composites and promote its industrialization process,the diatomite-based TiO2 composites was prepared by hydrolysis-deposition method.The effects of TiO2 loading amount on adsorption properties,the pho-tocatalytic performance and the whiteness of the composites were studied.The results show that the TiO2 loading amount has a great influence on the adsorption properties and photocatalytic performance of the composites,the photodegradation performance to the pollutant depends on the synergistic effect of the adsorption properties and the photocatalytic performance.The photodegradation performance of the composites is better when the TiO2 loading amount is 46%.The whiteness of the composites increases with the increase of TiO2 loading amount,and the whiteness is 91%when TiO2 loading amount is 46%,which can reach the standard of building and decoration materials on whiteness.
