Reduction of nitrogen oxides method....is this true?

Hi, in italy a big brand of ceramic present a new line of produtcs that promise:
Reduction of nitrogen oxides
Elimination of bacteria http://www.active-ceramic.com/

Is This true?
In America do you have yet this products?
Thank you very much!

Probably a dumb question but.... I didn't know that regular ceramics caused problems. Can you explain (on this forum please without links so that it doesn't look like spamming)

Sure I can try to answer you...

It is an extract from Active Ceramic's press room:

Exploiting the photocatalysis method - whereby a catalyst (in this case titanium dioxide) is able to react whenever sunlight or artificial light of an appropriate wavelength containing UVA rays shines on it, the air is cleaned of polluting organic substances, because oxidation makes the harmful organic substances harmless, bringing about three important actions:

1. the air is cleared of harmful organic and inorganic substances
2. surfaces are disinfected and bacteria removed
3. self-cleaning surfaces are created, exploiting the superhydrophilic effect created by the presence of the irradiated semiconductor (TiO2).

It should be noted that precisely because of its antibacterial properties, photocatalysis is also widely used in the textile industry, the cosmetics industry and in disinfection techniques in the healthcare sector.

Active Clean Air & Antibacterial Ceramic is the result of this methodology, and originates from a titanium dioxide treatment (which acts as a photocatalyst) carried out on the slabs at a high temperature.
The photocatalytic technology based on titanium dioxide is used in various ways in various branches of industry and methods are often based on nanotechnologies, a factor that in theory could cause a number of risks to health and to the environment during the manufacturing process.

I hope it's cleaner than before. So, I'd like to know if some of similar exists in USA...

OK, thank you for that explanation. I'm afraid though that I still don't understand how non-treated ceramic could be harmful for the health? I've not yet heard about ceramics containing bacteries. But, I am perhaps not 'up to date' with this.
