Description

Greenhouse gas emissions are one of, if not the major cause of global warming. With CO2 emissions rising annually, it is paramount to selectively capture and remove CO2 from flue gas. One method of capturing CO2 gas is via porous materials. Covalent organic frameworks (COFs) are porous materials which have been explored throughout this research. Two important features of COFs are the base unit linkage types (BULTs) and the functional groups attached to the organic linkers (OLs). The BULT used in this research was a covalent triazine framework (CTF) and the main functional group used in the OL was NH3. Both CTF and NH3 when used in other COFs improved overall selectivities for CO2. NH3 in tandem with electron withdrawing groups would theoretically make the N-H bonds more acidic, thus increasing the overall affinity further of the COF. In this research the process in synthesizing the COF is explored in detail as well as the affinity of molecules with CO2.
