Direct air capture (DAC) of CO₂ using solid sorbents offers a promising alternative to conventional amine scrubbing due to lower regeneration energy, higher selectivity, and improved stability. In this study, a hydroxyl-rich porous organic polymer (OPTP-8) was synthesized and subsequently functionalized with (3-aminopropyl)trimethoxysilane (APTS) to yield OPTP-8-APTS, a material designed for efficient low-pressure CO₂ capture.
