Raman Study of Clay/TiO2 Composites

Popis výsledku v původním jazyce

Isolated nanoparticles are generally known to have negative impact on living organisms. Some types of engineered nanoparticles, e.g. titanium dioxide nanoparticles (TiO2), show photocatalytic activity after UV light exposure and if they are tightly anchored to suitable type of matrix, they demonstrate their photodegradable properties together with lower environmental risk due to decreased mobility of nanoparticles. TiO2 nanoparticles are able to eliminate organic pollutants from air, as well as from waste water, however the photocatalytic properties are highly influenced by parameters such as particle size and phase modifications. TiO2 occurs in three basic phase modifications, anatase, brookite and rutile. The anatase modification shows the highest photoactivity after UV light exposure compared to the other forms of TiO2. The work deals with study of two clay composites bentonite/TiO2 (BETI) and vermiculite/TiO2 (VETI). These composites were prepared with different content of TiO2 wer
