Abstract:
The invention relates to the use of carbon nanomaterials as a filtration material pervious to nitrogen dioxide and impervious to ozone. The invention also relates to the use of carbon nanomaterials having a specific surface, measured by the BET method, of 15 to 40 m2/g inclusive and a form factor, equal to the ratio (highest dimension/lowest dimension) of the nanomaterial, of 5 to 250 inclusive, as material for filtering a gas mixture containing nitrogen dioxide and ozone, being pervious to the nitrogen dioxide and impervious to the ozone. The invention can be used in the field of air pollution.
