A method of reducing at least one atmospheric oxidizing pollutant, such as
ozone, with a reducing agent comprises contacting the reducing agent with
the at least one atmospheric oxidizing pollutant, wherein the reducing
agent comprises a precious metalfree trap material, such as a zeolite,
including at least one trapped atmospheric reducing pollutant, e.g. a
hydrocarbon, whereby as the at least one atmospheric oxidizing pollutant
is reduced the at least one trapped atmospheric reducing pollutant is
oxidized.
