Abstract: Amine-functionalized organosilica materials are provided that have improved stability when exposed to oxidizing/oxygen-containing environments during cycling of temperature, such as the cycling of temperature that occurs when using a material as a sorbent during successive adsorption/desorption cycles. Methods of performing CO2 sorption/desorption with improved stability of the organosilica sorbent material are also provided. The improved stability is achieved in part by using amine-functionalized organosilica materials where the amine-functionalization is provided by functional groups that include primary amines but do not include secondary amines. Still further improvements in stability can be achieved when the functionalization is provided by a functional group that includes a primary amine while also not having any hydrogens on a carbon atom that is in the beta position relative to the primary amine.

Abstract: Various zeolites may be produced under hydrothermal synthesis conditions in the presence of a silicon atom source and a bis-pyridinium compound having a structure represented by formula (I). Q is an optionally substituted C1-C10 hydrocarbyl group and two Q may join to form a carbocyclic ring; n is an integer ranging from 0 to 5; m is an integer ranging from 0 to 5; n+m is greater than or equal to 1; and A is a spacer group containing 2 to about 10 atoms.

Abstract: A method can include heating an aqueous reaction mixture comprising a silicon source and a boron source and/or an aluminum source in the presence of a quaternary structure directing agent to a temperature of at least 75° C. to produce a zeolite. A composition can include a borosilicate zeolite, an aluminosilicate zeolite, or an aluminoborosilicate zeolite having a framework symmetry of C2/m and a unit cell with measurements of a of 3.5 Å to 4.5 Å, b of 20.1 Å to 21.1 Å, c of 15.5 to 16.5 Å, and β of 97° to 98°.

Abstract: An aluminosilicate zeolite may have a molar ratio of Si to Al of about 3 to about 10, a monoclinic space group C2/m with unit cell dimensions of a of 13.6 Å+/−5%, b of 21.7 Å+/−5%, c of 6.7 Å+/−5%, and β of 93°+/−3°, 12-ring pores along a c-axis having dimensions of 7 Å+/−5% by 6 Å+/−5%, and 8-ring pores along an a-axis having dimensions of 3 Å+/−5% by 3 Å+/−5%. Said aluminosilicate zeolites may be useful in hydrocarbon conversion processes, selective catalytic reduction of NOx, CO2 and/or N2 adsorption, carbonylation reactions, and the monoalkylamine and dialkylamine syntheses.
