摘要

The industrial scale capture of CO2 from flue gas streams is becoming an increasingly important environmental issue. However, many of the existing CO2 capture systems either have regenerative energy demands that are too high or are cost prohibitive. Apromising solution is the utilization of functionalized solid sorbents, such as porous polymer networks (PPNs). PPNs are attractive due to their inherent structural stability, flexibility, high surface areas, and ability to incorporate various functional groups within the chemical scaffold. Herein, a low cost, scalable alternative to common carbon capture systems using a series of robust mesoporous melamine‐formaldehyde resins (mPMFs) loaded with active alkylamine sorbents is presented, which is dubbed as the PPN‐150 family. The variants within this material class are differentiated based on the incorporation of functionalized dopants; small molecules added at low molar percent concentrations to impart additional functionality into the PPN in orderto achieve low cost noncovalent tethering of alkylamines. The cyanuric acid doped PPN‐151‐DETA (DETA = diethylenetriamine) demonstrate unique features such as improved cycling capacity and heat of adsorption. To show its scalability, PPN‐151‐DETA issuccessfully synthesized at the 250 g scale without loss of the sorbent properties.
