<p>Use of a large pore molecular sieve incorporating a dπ-donor guest material and having a pore diameter greater than about 4-Angstroms as agent for the non-catalytic sorptive decontamination of a non-π-acceptor gas or gaseous mixture comprising π-acceptor gas-phase pollutant. Preferred guest materials include Cu and Ag. The methods, compositions and devices of the invention are applicable to the decontamination of a range of non-πacceptor gases or gaseous mixtures such as air, oxygen, nitrogen, carbon dioxide, hydrogen, the inert gases, saturated hydrocarbon gases, and mixtures thereof, and containing a range of π-acceptor gas phase pollutants such as carbon monoxide, oxides of nitrogen, oxides of sulfur, ethylene, and mixtures thereof.</p> |
