Estimating the term…
The present invention relates in a first aspect to a catalytic composition comprising a catalytic mixture in a powdered state of a first catalyst having photo catalytic activity, a second catalyst being a low temperature catalyst and an adsorbent, whereby the catalytic composition comprises carbon nanotubes in an amount of at most 5 weight-% based on the amount of the catalytic mixture. Further, the present invention relates to a method for producing said catalytic composition according to the present invention. In addition, a catalytic device comprising the catalytic composition according to the present invention, optionally coated on a carrier is provided as well as a gas depolluting apparatus containing said catalytic composition according to the present invention or the catalytic device accordingly. Finally, the use of the catalytic composition or the catalytic device as well as the gas depollution apparatus is disclosed, in particular, for depollution of gases of volatile chemical contaminants as well as treatment of gas containing biological contaminants.
Catalytic composition, comprising:
A method for producing a catalytic composition containing a first catalyst having photocatalytic activity, a second catalyst different to the first catalyst being a low-temperature catalyst, an adsorbent present in form of a catalytic mixture, and carbon nanotubes, comprising:
The method according to claim 9, wherein the admixing of the carbon nanotubes with the particles of the catalytic mixture is performed by mingling the components in powdered dry form.
