“When I made the discovery, I was very impressed by the oxygen that I saw coming from the TiO2 because, essentially, I had been able to mimic photosynthesis. Like chlorophyll in plants I was using the power of the sun to break down water and create oxygen,” says Fujishima.
TiO2 has been instrumental in the development of air and water purification technologies as well as self-cleaning, anti-fogging and anti-staining applications.
The most pervasive and perhaps the most straightforward example of TiO2 applications is that of self-cleaning buildings. Tiles and other surfaces coated with TiO2 stay clean thanks to the properties of the substance. Sunlight causes oxidation that breaks down grime while the superhydrophilicity of the substances causes the water to spread, washing surfaces clean. Air purifiers and anti-fog mirrors are two other popular applications.
“TiO2 can break down water, kill bacteria, and deodorize by getting rid of odors like that of tobacco or pets. It is truly an incredible substance,” Fujishima says.
Svinjska mast moze da posluzi, ali i premazivanje sa TiO2. ^ :)
Ne znam zasto sam zapamtio da je proziran, mozda iz onog videa gde ga prskaju svuda a ne primeti se posle nista. :D
Mada to mudro rade uglavnom na svetlim i belim povrsinama...
