FUNCTIONALIZED MATERIAL FOR SELECTIVE REMOVAL OF SMOKE CONSTITUENTS

A smoking article includes a filter containing a metal oxide-functionalized activated carbon material. The metal oxide-functionalized activated carbon material selectively reduces amounts of aldehydes in mainstream smoke. MgO- and CaO- functionalized activated carbon materials are particularly effec...

Zusammenfassung:	A smoking article includes a filter containing a metal oxide-functionalized activated carbon material. The metal oxide-functionalized activated carbon material selectively reduces amounts of aldehydes in mainstream smoke. MgO- and CaO- functionalized activated carbon materials are particularly effective at selectively capturing acetaldehyde.
