ABSTRACT:
A nitrogen oxide absorbing material, comprising a hollandite-type complex oxide having main metal elements comprising minimally of aluminum and tin, or zinc and tin, and a method of using that nitrogen oxide absorbing material comprising the steps of contacting the nitrogen oxide absorbing material with a gas containing nitrogen oxides. The method of reducing the adsorbed nitrogen oxides on the nitrogen oxide absorbing material includes the steps of releasing the nitrogen oxides from the nitrogen oxide absorbing material, and of reducing the released nitrogen oxides with a three way catalyst or other nitrogen oxide reducing catalysts.
