Abstract
A composite material is provided for the removal of ozone from a gaseous stream, which is made of a support matrix having coated on its surface an adhering layer of fine particles of Hopcalite. The support matrix is preferably made of a material that has a relatively board transition region. A particularly preferred material for the matrix is a polymeric ethyl vinylacetate.
