Abstract
Layered adsorbent-substrate composites are prepared by methods comprising heating the surface of an aluminum substrate, contacting the surface of the substrate with a slurry containing the adsorbent and a binder, and heating the coatings to form hardened surfaces which can have excellent adsorption and mechanical properties and have a variety of uses such as adsorbents in automobile mufflers.
