An interesting case study in this regard are γ-cyclodextrin metal-organic frameworks (CD-MOFs). These CD-MOFs have recently been demonstrated to leverage labile hydroxidebased chemistry to achieve promising CO 2 capture performance under flue gas conditions. The best performing MOF in this family, KHCO 3 -CD, demonstrated thermal, oxidative and cycling stabilities along with reasonable capacities for post-combustion CO 2 capture (1.43 mmol g -1 @ 15% CO 2 /85% N 2 , 30 • C and approx. 0.06 mmol g -1 @ 0.4 mbar CO 2 , 25 • C). A bicarbonate capture mechanism involving non-metal bound hydroxide counter ions within the framework pores (eq. 2)
