The present invention relates to a composition comprising mesoporous silica grafted with an ionic liquid to form a mesoporous silica composition that provides polar gas/non-polar gas and alkene/alkane separation Desired functionality, adsorption, specific surface area functionalization, and selectivity levels. A specific example uses silylated 3,3'-(2,2-bis(hydroxymethyl)propane-1,3-diyl)bis(1-methyl-1H-imidazol-3-ium)bis-( Trifluoromethyl-sulfonyl)amide was used as the ionic liquid. The mesoporous silica composition can be configured, for example, as a membrane. |
